/kind bug

What happened:

Manila's grant access API is asynchronous, and it doesn't guarantee that the access rules are applied. There are cases, when the rules state may still be queued_to_apply.

What you expected to happen:

Manila CSI driver must wait until the access rules state is active before trying to mount the share. If the timeout is reached or the access rule is in error state, CSI driver must delete the access rule and return an error, so the next reconcile loop can create it from scratch.

How to reproduce it:

n/a
