When using baremetal driver, genericswitch needs to be listed first

Was having issues rebuilding my cluster when I could not get neutron to adjust the switch port vlans properly EXCEPT when deleting the baremetal instance. I discovered this post:

https://storyboard.openstack.org/#!/story/2008686

which explained an issue where the user needed "genericswitch" to be listed before "baremetal" in the ml2_conf.ini

By changing the configuration from:

mechanism_drivers = openvswitch,l2population,baremetal,genericswitch

to:

mechanism_drivers = openvswitch,l2population,genericswitch,baremetal

it allowed neutron to properly configure switch ports upon provisioning and moving the port to the proper tenant network.

This isnt necessarily a bug in the neutron code, but needs to be a big red "BE AWARE" notice when configuring either baremetal networking AND the Generic Switch driver.
