Cache endpoint responses on a per-principal basis

Browse Source 
Previously, any HTTP request to an endpoint that included a principal
would bypass the cache. This prevented authenticated requests from
making use of the cache and its configurable time-to-live.

This commit updates the caching operation invoker to include the
principal, if any, in its cache key. As a result, requests that
include a principal will make use of the cache, potentially returning
the result of a previous invocation of the same endpoint by the same
principal.

Closes gh-19538

NOTE: The prefix `management.endpoint.<name>` is used to uniquely identify the endpoint that is being configured.
NOTE: When making an authenticated HTTP request, the `Principal` is considered as input to the endpoint and, therefore, the response will not be cached.
