Caching: Refactor enterprise query caching middleware to a wire service (#65616)
* define initial service and add to wire

* update caching service interface

* add skipQueryCache header handler and update metrics query function to use it

* add caching service as a dependency to query service

* working caching impl

* propagate cache status to frontend in response

* beginning of improvements suggested by Lean - separate caching logic from query logic.

* more changes to simplify query function

* Decided to revert renaming of function

* Remove error status from cache request

* add extra documentation

* Move query caching duration metric to query package

* add a little bit of documentation

* wip: convert resource caching

* Change return type of query service QueryData to a QueryDataResponse with Headers

* update codeowners

* change X-Cache value to const

* use resource caching in endpoint handlers

* write resource headers to response even if it's not a cache hit

* fix panic caused by lack of nil check

* update unit test

* remove NONE header - shouldn't show up in OSS

* Convert everything to use the plugin middleware

* revert a few more things

* clean up unused vars

* start reverting resource caching, start to implement in plugin middleware

* revert more, fix typo

* Update caching interfaces - resource caching now has a separate cache method

* continue wiring up new resource caching conventions - still in progress

* add more safety to implementation

* remove some unused objects

* remove some code that I left in by accident

* add some comments, fix codeowners, fix duplicate registration

* fix source of panic in resource middleware

* Update client decorator test to provide an empty response object

* create tests for caching middleware

* fix unit test
