SOLR-16924: RESTORECORE: make UpdateLog ACTIVE without requiring
REQUESTAPPLYUPDATES (#1965)
RESTORECORE now sets the UpdateLog to ACTIVE state instead of requiring a
separate REQUESTAPPLYUPDATES call in Collection restore. The latter will still
happen in 9.x for backwards-compatibility.

> This is a refactoring improvement designed to simplify & clarify a step in
> collection restores. One of the final phases of RestoreCmd (collection
> restore) is to call REQUESTAPPLYUPDATES on each newly restored replica in
> order to transition the state of the UpdateLog to ACTIVE (not actually to
> apply updates). The underlying call on the UpdateLog could instead be done
> inside RESTORECORE at the end with explanatory comments as to the intent. I
> think this makes more sense that RESTORECORE finish with its UpdateLog ready.
> And it's strange/curious to see requests in the cluster to apply updates
> from an updateLog when there is none to do! Adding clarifying comments is
> important.
> See my comment:

> I think there isn't any back-compat concern.
