  Log Message:
  -----------
  HSEARCH-3118 Split the ElasticsearchWorkOrchestrator and ElasticsearchAccumulatingWorkOrchestrator interfaces and rename them accordingly

They are definitely different beasts, so let's not make one extend the
other.

  HSEARCH-3118 Remove the unnecessary awaitCompletion() method from ElasticsearchWorkOrhcestratorImplementor

This method was necessary in Search 5 when it was the only way to wait
for submitted works to be completed, but we now return
CompletableFutures that serve this exact purpose.

  Log Message:
  -----------
  HSEARCH-3118 Move the requirement to be non-blocking from Lucene works to orchestrators

We know we will not be able to use the index writer and reader in a
non-blocking way, so if we really need asynchronous behavior we will
have to use a thread in the orchestrator. So, let's acknowledge that
and move the complexity to the orchestrator.

anymore, which means in particular that someone trying to query a brand
new index will get exceptions because of missing files.

  HSEARCH-3118 Use a single, immutable analyzer in IndexWriterHolder

The mutable analyzer hack was only necessary to support specifying the
analyzer to use for each add/update operation.

That, in turn, was only necessary to support:

1. Indexing multiple entity types to the same index (it's no longer
supported)
2. or dynamic analyzer selection through @AnalyzerDiscriminator (which
is no longer supported either).

So it's safe to remove this hack.
