   …HARED replica concurrent updates
   https://github.com/apache/lucene-solr/pull/983/commits/581f468f9914ce2488201efbed42fd43dc4b481
   
   - Pull read lock is only required before the local indexing starts. If indexing has to pull it can acquire and release write lock without anything to do with read lock first. Removing the unneeded lock upgrade/downgrade logic to simplify things.
   - Added one pager explanation in the start of SharedCoreConcurrencyController around overall concurrency design.
   - Added mores comments around BlobCoreMetadata#generation number and its usage.
