SOLR-15983: parallel log replay now uses separate UpdateRequestProcessor
objects (#601)
* parallel log replay now uses separate UpdateRequestProcessor objects
* executor local variable in UpdateLog.doReplay can be null
* Use a ThreadLocal of the URP to avoid re-creating and avoid excessive
finish() calls and to make it clearer that the URPs are used correctly (have
correct lifecycle and aren't shared).
* remove unused procThreadLocal member in favour of local variable with same
name
* just one for-loop on procPool to finish-and-close
* add solr/CHANGES.txt entry
