Add quotas to Cisco N1kv plugins supported extension aliases

When using stable/icehouse branch, due to missing quotas extension,
VM bring up errors out. With the quota table now being created as
part of folsom_initial, adding quotas to supported extension aliases
in the N1kv plugin will fix the VM bring up issue.
