More control and visibility over Geo-replicated subscriptions

[shasank112001]

I noticed that in pulsar we can disable automatic creation of subscriptions, however, the properties and nature of the subscription can be overriden by clients. This is not that big of a problem, until you take geo-replication into consideration.

What I want to achieve is disabling clients from turning geo-replication on or off on a subscription, that was created for them. However, even if I make a custom authorization class, there doesn't seem to be any way to disable this behaviour.

Moreover, there is a lack of logging and alerting when a change is made to a subscription. If you have any suggestions on how to disable or log this behaviour, I would appreciate it.

There's "PIP-398: Subscription replication on the broker, namespace and topic levels" #23770 by @nodece in progress which seems to be related to your requirement.

I will continue to work on PIP-398.
