DELETEREPLICA command shouldn't delete de last replica of a shard

[Yago Riveiro]

I don't know if this behaviour makes sense but in my IMHO the last replica of
a shard should be removed only by the DELETESHARD command ...

If you don't not notice about this behaviour, the result is the deletion of
the whole shard, and as a consequence, the deletion of the shard in the
clusterstate.json ... with all the pain associated.

There is a related, but maybe not exactly same, JIRA:
https://issues.apache.org/jira/browse/SOLR-5209

I see your point. In the custom routing case where it _is_ reasonable
to delete all replicas in a shard, DELETESHARD does the trick.

It's reasonable to raise a JIRA I think so we have a record of the
discussion/decision.
