commit dbb7dd03fea68120ef5ac9bbb1b3f184e3f2eacc
Author: Andrew Laski <[email protected]>

    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.
    
    Based on commit d4056f8723cc6cefb28ff6e5a7c0df5ea77f82ef but modified
    for the backport.
    
    Closes-Bug: #1290537
