* Additional options to KnnGraphTester to support benchmarking with ann-benchmarks
* switch to parallel array-based storage in HnswGraph (was using LongHeap)
* LUCENE-9617: Reset lowestUnassignedFieldNumber in FieldNumbers.clear()
FieldNumbers.clear() is called from IndexWriter.deleteAll(), which is
supposed to completely reset the state of the index. This includes
clearing all known fields.
Prior to this change, it would allocate progressively higher field
numbers, which results in larger and larger arrays for
FieldInfos.byNumber, effectively "leaking" field numbers every time
deleteAll() is called.

SOLR-13027 Use TestInjection so that we always have a Tragic Event
When we encounter a tragic error in the index writer, we can trigger a
leader election instead of queing up a delete and re-add of the node in
question. This should result in a more graceful transition, and the
previous leader will eventually be put into recovery by a new leader.
closes#2120
Files in org.apache.lucene.search.comparators package
has a wrong indent of 4 spaces instead of 2.
This patch fixes only the indent from 4 to correct 2 spaces
Prior to this change, it was not feasible to write a custom aggregate function in plugin code
because the FacetContext class did not expose its fields for access outside its package. Also
some of the useful abstract classes for SlotAcc were package-private too
Adds two metrics to the SolrCloud Overseer: solr_metrics_overseer_stateUpdateQueueSize and solr_metrics_overseer_collectionWorkQueueSize with corresponding entries in the the Prometheus exporter's default/stock configuration.

Disable sort optimization in comparators on index sort.
Currently, if search sort is equal or a part of the index sort, we have
an early termination in TopFieldCollector.
But comparators are not aware of the index sort, and may run
sort optimization even if the search sort is congruent with
the index sort.
This patch:
- adds `disableSkipping` method to `FieldComparator`,
This method is called by `TopFieldCollector`, and currently called
when the search sort is congruent with the index sort,
but more conditions can be added.
- disables sort optimization in comparators in this case.
- removes a private `MultiComparatorLeafCollector` class, because the only
class that extends `MultiComparatorLeafCollector` was `TopFieldLeafCollector`.
The logic of the deleted `TopFieldLeafCollector` is added to `TopFieldLeafCollector`.
