[FIX] auditlog: registry propagation

When a new auditlog rule is added / modified / deleted, all workers
need to be notified of the change. This is done through registry
signaling. The previous code was not using the proper level of signaling
resulting in workers not being aware of the changes and not implementing
the correct auditlog rules, because they had only invalidated their
cache and not reloaded the registry.

We fix this by using the same signaling as implemented in
`base_automation` which sets the the registry_invalidated field of
env.registry to True to cause a full registry reload.
