Description

Revert SOLR-15748 – remove v2 /api/cluster being a CLUSTERSTATUS call

The information (e.g. aliases, or the status of one collection, live nodes, etc.) should be made available via V2 but we don't need a macro API to return a bunch of these things at once, which is what CLUSTERSTATUS is.  I suspect CLUSTERSTATUS may have been one of the original SolrCloud level APIs so it became a kitchen sink of all things about the state/status.  In hindsight, I don't agree with it.  It ends up blowing up in size for clients that only need a subset of it, leading to decomposing it – SOLR-17381.
