[FEATURE] Implement circuit breaker to allow resource protection for managed services

[JohannesDaniel]

As a provider of a managed service of OpenSearch, I need to be able to protect resources such as memory in the service.

Therefore, the plugin is expected to check for each creation or updating of feature sets and models, whether the consumed resources exceed a limit and to throw a LimitExceededException if this is the case (instead of applying the creation / update).

This affects TransportFeatureStoreAction, TransportCreateModelFromSetAction, TransportAddFeatureToSetAction.

The circuit breaker shall be implemented for memory, but should be easily enhanceable by other resource types (e.g. CPU).
