This changes how `min_score` is implemented both for `function_score` and the
search request parameter to confirm whether the minimum score is met in the
`matches()` phase of a TwoPhaseIterator.
Today if a shard is marked as inactive after a heavy indexing period
large merges are very likely. Yet, those merges are never committed today
since time-based flush has been removed and unless the shard becomes active
again we won't revisit it.
Yet, inactive shards have very likely been sync-flushed before such that we need
to maintain the sync id if possible which this change tries on a per shard basis.
The test spawns up 3 nodes, waits for a master to be elected and starts network disruptions. If those kick in too early we may have a cluster with a state not recovered block which causes failure during clean ups. http://build-us-00.elastic.co/job/es_core_master_oracle_6/3034/
* Allow for multiple host specifications (e.g. _en0_,192.168.1.2,_site_).
* Add _site_ and _global_ scopes as counterparts to _local_.
* Warn on heuristic selection of publish address.
* Remove the arbitrary _non_loopback_ setting.

The @IndexSettings annoationat has been used to differentiate between node-level
and index level settings. It was also decoupled from realtime-updates such that
the settings object that a class got injected when it was created was static and
not subject to change when an update was applied. This change removes the annoation
and replaces it with a full-fledged class that adds type-safety and encapsulates additional
functionality as well as checks on the settings.
Today IndicesLifecycle is a per-node class that allows to register
listeners at any time. It also requires to de-register if listeners
are not needed anymore ie. if classes are created per-index / shard etc.
They also cause issues where listeners are registered more than once as in #13259
This commit removes the per-node class and replaces it with an well defined
extension point that allows listeners to be registered at index creation time
without the need to unregister since listeners are go out of scope if the index
goes out of scope. Yet, this still allows to share instances across indices as before
but without the risk of double registering them etc.
All data-structures used for event notifications are now immuatble and can only changes
on index creation time. This removes flexibility to some degree but increases maintainability
of the interface and the code itself dramatically especially with the step by step removal of
the index level dependency injection.
Closes#13259
The ExtensionPoint.ClassSet binds adds the extension classes to a a Multibinder and binds
the classes and calls the asEagerSingleton method on the multibinder. This does not actually
create a singleton. Instead we first bind the class as a singleton and add then add the class
to the multibinder.
Closes#14194
