    Include cisco plugin in migration plugins with ovs
    
    Currently we have many migration files with
    missing cisco plugin in migrate_plugin when
    ovs is included.This causes missing tables
    when cisco plugin is enabled and migration is run.
    This fix should automatically include the cisco
    plugin if ovs is detected in the migrate_plugins.
    
    Closes-Bug: #1292114
