    Add RBAC policy for ec2 API security groups calls
    
    The revoke_security_group_ingress, revoke_security_group_ingress, and
    delete_security_group calls in the ec2 API were not restricted by policy
    checks.  This prevented a deployer from restricting their usage via
    roles or other checks.  Checks have been added for these calls.

Title:
  RBAC policy not enforced when adding a security group rule using EC2
  API (CVE-2014-0167)

Bug description:
  
  It seems that when using the EC2 API, the security group implementation does not enforce RBAC policy for the add_rules, remove_rules, destroy and other functions (in compute/api.py). Only the add_to_instance and remove_from_instance functions enforce RBAC. This seems like an oversight for obvious reasons.

  The Nova API security group implementation does enforce RBAC on these
  functions.

  In addition, the add_to_instance and remove_from _instance functions
  which are wrapped in RBAC verification use the
  "compute:security_groups" action which is not even listed in the
  default /etc/nova/policy.json. The latter is confusing to users.

  This is the case on Grizlly and at first glance, it doesn't look like
  this has changed in Havana.
