remove cluster names from sample config

We dont need users to specify cluster names
anymore since managed cluster names will be
auto detected and hub cluster name will always
be hub.

Also removed cluster name lookup from envfile
since drenv conf will not have cluster names anymore.

These changes are due  to feature added in ramen/e2e:

- RamenDR/ramen#1866
