Allow blocked XREAD on a cluster replica (#7881)
I suppose that it was overlooked, since till recently none of the blocked commands were readonly.

other changes:
- add test for the above.
- add better support for additional (and deferring) clients for
  cluster tests
- improve a test which left the client in MULTI state.
