Restservers aren't advertised?

[nightkr]

Description

As far as I can tell we don't advertise the restservers anywhere (discovery, UI, etc). The getting started guide "just" uses the rolegroup Service.

We should verify that this is the case and if so add restservers to discovery.

Motivation

• consistency

Note

Added by @adwk67 The aim here is not to implement full discoverability for role endpoints; that should be done when we tackle that for all operators. We actually reached a point in the original implementation of HBase listener-endpoints where there was a config map (like kafka, hdfs etc.) that listed the endpoints by pod/replica, and at that point we decided against doing that as

• it would have been premature without knowing what discovery-2.0 would look like in general (naming, structure etc.), and
• we didn't want to implement and advertise something that could then become a breaking change later on.

So I understand the scope of this ticket to be about bringing the rest-server inline with the other roles, without claiming this to be the final destination.
