Subject: [PATCH] Do not delete all search indexes when reindexing specific
 models (#16755)

* Do not delete all search indexes when reindexing specific models

* Clear all indexes only if neither --lazy nor a list of models are
  specified for "manage.py reindex"

* Otherwise, clear the index for a model immediately before rebuilding
  it

* Separated clearing from re-indexing the search cache
