Allow update of the event filter on the persistent subscription group

[epitka]

Is your feature request related to a problem? Please describe.
When releasing new code that handles additional events using persistent subscription, I need a way to update event filter on existing persistent subscription.

Describe the solution you'd like
Expose option on UpdateAllAsync to allow for modification of the group subscription filter.

Describe alternatives you've considered
Creating persistent subscription group per each event within microservice. This would potentially end up creating huge number of persistent subscription group, as multiple microservices might handle same event and each one would have to create separate subscription.

Additional context
I my use case, whenever a new event handler is added, it always starts from end, as it is a new functionality that is being added and we want to handle it from the time it is deployed.

Quick thoughts / questions :
would deleting and recreating a new one work for you ?

• What about the parked stream ?

• What about the parked stream ?

How would deleting work, how would I know from where to start new subscrition?
