Bug Description

With switch_heartbeat disabled, a traceback is logged during VM deletion after a Nexus reboot.

Steps to repro:
1. Disable switch_heartbeat.
2. Launch a VM.
3. Verify the Nexus switch is configured correctly.
4. Reboot the Nexus switch.
5. Upon boot up, verify the Nexus switch is not configured.
6. Delete the VM.
7. Note the traceback in screen-q-svc.log.

Delete fails after switch reset (replay off)

    Many changes have occurred since this bug was written. We now have
    a newer N9K image and dhcp port entries are now created when the CLI
    'neutron subnet-create' is executed. I went thru the steps as
    defined by the bug. The first failure after switch restart is due
    to the ncclient session being stale (fixed by 1399998). This is
    expected when replay is not enabled. When attempting delete on
    2nd retry when ncclient session new, the N9K switch returns the error
    message 'None of the VLANs exist'. This changeset accepts this
    message as an acceptable condition and prevents exceptions from
    bubbling up to higher layer.

ML2 cisco_nexus MD: VLAN not created on switch

    As described in DE588,
    "With neutron multiworkers configured, there is a potential race condition
    issue where some of the VLANs will not be configured on one or more N9k
    switches.

    /etc/neutron/neutron.conf
    -------------------------
    api_workers=3
    rpc_workers=3"

    Fix is to allow the vlan create command to be sent down to a switch
    under most event conditions. Long term fix will be to introduce a new
    column in the port binding DB table that indicates the true state of the
    entry/row.

Create knob to prevent caching ssh connection

    Create a new initialization knob named never_cache_ssh_connection.
    This boolean is False by default allowing multiple ssh connections
    to the Nexus switch to be cached as it behaves today. When there
    are multiple neutron processes/controllers and/or non-neutron ssh(xml)
    connections, this is an issue since processes hold onto a connection
    while the Nexus devices supports a maximum of 8 sessions. As a result,
    further ssh connections will fail. In this case, the boolean should be
    set to True causing each connection to be closed when a neutron event
    is complete.

Bubble up exceptions when Nexus replay enabled

There are several changes made surrounding this bug.

    1) When replay is enabled, we should bubble exceptions
       for received port create/update/delete post_commit
       transactions. This was suppressed earlier by
       1422738.

    2) When an exception is encountered during a
       post_commit transaction, the driver will no longer
       mark the switch state to inactive to force a replay.
       This is no longer needed since 1481856 was introduced.
       So from this point on, only the replay thread will
       determine the state of the connection to the switch.

3) In addition to accommodating 1 & 2 above, more detail
data verification was added to the test code.

Quick retry connect to resolve stale ncclient handle
    
    When the Nexus switch reboots, OpenStack Nexus Driver will be left
    with a stale ncclient handle resulting in an exception.  When an
    exception is encountered, another retry is performed within the driver.
    The first exception information is saved so if the second exception
    fails again, we report on the first exception.
    As part of this fix, I've removed code which supports 2 versions
    of ncclient since the older version no longer meets the version
    configured in our requirements.txt.

Remove duplicate entrypoints in setup.cfg
    
    Delete the entrypoints that are duplicates of neutron's entrypoints.
    Duplicate entrypoints cause packaging to fail.
    
    This is a cherry pick from master, but in master the driver entrypoints
    were cleaned up by driver decomposition patches. In this patch for stable
    we simply remove the driver entrypoints since they are still in neutron
    stable/kilo core.

Cisco UCSM driver updates to handle duplicate creations
    
    Each create, delete or update operation on the UCS Manager is part of its own
    transaction to handle duplicate creations on UCS Manager better. So, when a
    create operation, tries to create something that already exists, the plugin
    correctly ignores the duplicate exception and proceeds to the next step
    (instead of skipping it).

Replace retry count with replay failure stats
    
    This code-set eliminates checking switch config replay attempts against
    max configurable attempts.  Instead it will continue to contact the
    switch forever.
    
    I've repurposed some of the logic to provide statistics to
    identify if there are issues in replay process.  There are two
    statistics: 1) contact 2) config.  The contact stat identifies
    a problem contacting the switch.  The operator would need to
    see if there is something wrong with the nexus switch or the path
    to the switch. The config stat identifies an issues with the config
    set we're trying to send to the switch.  This latter case may require
    part of the config to be removed.

ML2 cisco_nexus MD: Multiprocess replay issue
    
    When api or rpc_workers are set > 0 replay is not working in multi-node setups.
    Issue is that access to nexus switches is to set to False (can't access) by
    default in the monitor code. In multiprocess configurations the monitor
    thread (thread code determines if switch is accessible) only runs in the
    main process (mech_cisco_nexus.py initialize() method is only called once,
    regardless of number of processes). In all other processes the "access
    switch" setting never gets set to True (can access).
    
    This patch allows all non-parent processes to continue event handler
    processing. Only the parent process (which starts the monitor thread) will
    verify if the switch is accessible during event processing.

ML2 cisco_nexus MD: If configured, close ssh sessions
    
    Most (if not all) Nexus switches have a limit of eight ssh sessions open
    at one time. With the openstack/neutron introduction of rpc and api workers
    (setting these variables results in additional neutron-server processes
    being forked) when more than eight processes are in use (including one for
    the parent neutron-server process) the ssh limit on the nexus switches is
    exceeded and exceptions are taken. More importantly is that communication
    to the nexus switches can not be made for the nineth (or above) processes.
    
    This nexus switch limitation will be fixed by closing each session after
    each event if the overall number of processes is >= eight.

Delete fails after switch reset (replay off)
    
    Many changes have occurred  since this bug was written.  We now have
    a newer N9K image and dhcp port entries are now created when the CLI
    'neutron subnet-create' is executed.  I went thru the steps as
    defined by the bug. The first failure after switch restart is due
    to the ncclient session being stale (fixed by 1399998).  This is
    expected when replay is not enabled.  When attempting delete on
    2nd retry when ncclient session new, the N9K switch returns the error
    message 'None of the VLANs exist'.  This changeset accepts this
    message as an acceptable condition and prevents exceptions from
    bubbling up to higher layer.

Ensure that we're neutron stable/kilo compatible
    
    This patch both reverts a patch that made us incompatible with neutron
    stable/kilo and updates the requirements.txt and tox.ini so that it will
    install neutron stable/kilo for UTs and also ensures "python setup.py
    install" verifies that a compatible version of neutron is installed.
    
    This reverts commit 3d9b38c758e49db0798e6bad3607c6bcd203d065.

Send tenant_id 0 for shared networks to VSM
    
    We need to indicate if a network is shared for VSM. In order
    to do so, we will now send tenant_id = '0' for shared networks. This
    change additionally ensures the tenant_id is properly updated when the
    network is updated to be a shared network after it is created.
    
    Also removed broken test case in monolithic plugin UTs and fixed
    copyright lines in UT files.

Implement update port for N1kV ML2 mechanism driver
    
    Added support for update port operation in order to have this operation
    work successfully. On update port we check if this is the the first time
    binding of a router or DHCP port as currently that is the only operation
    we want to support updates for.
