Honestly, I don't think supporting neutron plugins without quota support
is something we should do. That optionality adds to many permutations to
the matrix.

Title:
  VM launch fails always when using particular Neutron plugin

Status in OpenStack Compute (Nova):
  Opinion

Bug description:
  When I tried devstack with Neutron Ryu plugin, VM launch failed with the following error:
  ERROR: The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-2f3489c9-9fb5-4666-b5a3-dabf8068160b)

  Change Iaaee059a (https://review.openstack.org/#/c/49455/) added the validation of the port quota via Neutron API.
  However, Neutron Quota API  is an extended API. Therefore, this API isn't provided when using Neutron plugin which doesn't support Quota extension and it causes 404 if the API is called.

  
  The following error message appeared in screen-n-api.log:

  REQ: curl -i http://192.168.0.10:9696/v2.0/quotas/d2b5645336864565a3b5110e31cbe096.json -X GET -H "X-Auth-Token: <...>" -H "Content-Type: application/json" -H "Accept: application/json" -H "User-Agent: pytho
