Configure plugins by name

To configure core plugin or service plugins, instead of using class names,
simpler names can also be used, ex:

service_plugins = router, firewall, lbaas

For compatibility with previous versions, the class name of a plugin can be
specified instead of its entrypoint name, ex:

service_plugins = router, neutron.services.firewall.fwaas_plugin.FirewallPlugin, lbaas

Check if a key exists before deleting

Before blindly deleting a key from a dictionary, check if the key exists
first. This prevents the ODL MechanismDriver from getting out of sync
with ODL and entering a constant "sync_full" state. This also allows 50
VMs to be spawned at once.
