Expected workflow:

1) Add access rule to a snapshot

$ manila access-allow snapshot1 ip 0.0.0.0
<CLI waits on the the access rule to transition to "active" state" before returning to the prompt>

2) Deny access to a snapshot

$ manila access-deny snapshot1 f7320b78-994e-4e2f-b955-c649bb41fd74
<CLI waits for access rule to be removed from the snapshot before returning to the prompt>
