* Add accounting circuit breaker and track segment memory usage This commit adds a new circuit breaker "accounting" that is used for tracking the memory usage of non-request-tied memory users. It also adds tracking for the amount of Lucene segment memory used by a shard as a user of the new circuit breaker. The Lucene segment memory is updated when the shard refreshes, and removed when the shard relocates away from a node or is deleted. It should also be noted that all tracking for segment memory uses `addWithoutBreaking` so as not to fail the shard if a limit is reached. The `accounting` breaker has a default limit of 100% and will contribute to the parent breaker limit. Resolves #27044 |
