  HSEARCH-3775 Use reference counters to close index readers

... and consequently remove the concept of DirectoryReaderHolder:
we won't be needing it if we always use reference counters.

  HSEARCH-3775 Implement forced refreshes in LuceneWriteWorkProcessor

Essentially, after this change, it is possible to write to the index and
force the change to be visible to search queries without requesting a
commit.

Before this change, we would systematically commit in order to make the
changes visible, which 1) is overkill and 2) is not effective when a
refresh_interval different from 0 is configured.
