Hard-coded /rests endpoint in stream locations

We creating streams name using hard-coded constant RestconfConstants.BASE_URI_PATTERN.

This issue is on 6.0.x and 5.0.x branch in SubscribeToStreamUtil class. We get uriInfo as a parameter here from which we should set the base uri. But this is not the case, and we are replacing the restconf uri with RestconfConstants.BASE_URI_PATTERN which is constantly set to "rests".

This causes issues like:

It means client configuration is ignored and "rests" is always used. Fix that.
