    Propagate vendor_data from nova-cloud-controller

    When using DVR and L3HA neutron deployment options,
    Nova API Metadata requests are served from compute nodes,
    instead of from neutron-gateway nodes.

    This change allows nova-compute to receive vendor_data
    configuration values from nova-cloud-controller charm
    relation and write to nova-compute's nova.conf
    appropriately.

    This will be effictive for Queens and later OpenStack
    releases.

    Synced charm-helpers in order to import new context
    for writing the vendor_data.json file.
