 Title: #5343: autofs: distinguish between empty cache and offline state
Action: opened

PR body:
"""
If the cache is empty and SSSD is offline we now return a proper
error code to autofs so it can iplement a proper retry logic to
fetch the maps when SSSD comes back offline.

This also requires changes in autofs which are not yet available
so the best way to test it with SSSD is to use the autofs test
tool (autofs_test_client) to see that it returns correct error
codes.
