This commit introduces CPU based circuit breaker. This circuit breaker
tracks the average CPU load per minute and triggers if the value exceeds
a configurable value.
This commit also adds a specific control flag for Memory Circuit Breaker
to allow enabling/disabling the same.
This commit introduces two functionalities: request rate limiting and ability to identify requests based on type (indexing, search, admin). The default rate limiter rate limits query requests based on configurable parameters which can be set in web.xml. Note that this rate limiting works at a JVM level, not a core/collection level.
* include missing RESTORE parameters
* small grammer fix
* remove duplication of describing the parameters in favour of the pattern of pointing to the CREATE command documentation.
This adds a lot of "under the covers" improvements to how JSON Faceting FacetField processors work, to enable
"sweeping" support when the SlotAcc used for sorting support it (currently just "relatedness()")

* SOLR-14588: Implement Circuit Breakers
This commit consists of two parts: add circuit breakers infrastructure and a "real" JVM heap memory based
circuit breaker which monitors incoming search requests and rejects them with SERVICE_TOO_BUSY error
if the defined threshold is breached, thus giving headroom to existing indexing and search requests
to complete.
* SOLR-14588: Implement Circuit Breakers
This commit consists of two parts: initial circuit breakers infrastructure and real JVM memory based
circuit breaker which monitors incoming search requests and rejects them with SERVICE_TOO_BUSY error
if the defined threshold is breached, thus giving headroom to existing indexing and search requests
to complete.
* Add an example explaining how to use
* fix up JavaDoc formatting
* add missing SearchComponents that ship with Solr, and point to external site with components.
* fix path
* simplify page layout by consolidating to lists
* add missing components that are documented elsewhere in refguide
* try to get pathing to pass precommit
* remove mention of solr.cool, in favour of a seperate PR that handles it differently
