Prior to this commit, exceptions nested in
`NestedServletExceptions` would not be recorded by the
`WebMvcMetricsFilter`. This commit ensures that exceptions
happening downstream (e.g. happening while writing the response
body itself) are properly recorded.

Update the `BaseConfiguration` class in `ScheduledTasksEndpointTests`
to be package private so that it can be enhanced by cglib.
Prior to merge commit 361437f4 the class was a lite configuration so
it didn't matter that it was a private class.
When Spring Security is misconfigured it's possible to switch from an anonymous user
to a normal user. When switching back again, the corresponding
AuthenticationSwitchUserEvent will have a null target user. Previously, Actuator's
AuthenticationAuditListener would throw a NullPointerException when it received such an
event.
This commit updates the audit listener to defensively handled events with a null target
user.

Prior to this commit, the `HttpTraceWebFilter` would collect the
response information (status and headers) for tracing purposes, after
the handling chain is done with the exchange - inside a
`doAfterSuccessOrError`.
Once the handler has processed the exchange, there is no strong
guarantee about the HTTP resources being still present. Depending on the
web server implementation, HTTP resources (including HTTP header maps)
might be recycled, because pooled in the first place.
This commit moves the collection and processing of the HTTP trace right
before the response is committed. This removes the need to handle
special cases with exceptions, since by that time all exception handlers
have processed the response and the information that we extract is the
information that's about to be written to the network.
Fixes gh-15819
This commit aligns the Spring WebFlux instrumentation on Spring MVC
since gh-12447.
From now on, if the best matching path pattern is not found,
the recorded uri tag will be "UNKNOWN".
Note that for WebFlux.fn, the pattern information is properly
recorded as of SPR-17395.

This commit adds more information to the ElasticSearch REST
health indicator.
When the ES instance responds with an error HTTP status,
the health details now include the actual status code and reason phrase.
When the ES instance returns a HTTP 200 response, the entire response
map is used as health details.
See gh-15366
This commit adds `ElasticsearchRestHealthIndicator`, a new
`HealthIndicator` for Elasticsearch, using the Elasticsearch "low level
rest client" provided by the
`"org.elasticsearch.client:elasticsearch-rest-client"` dependency.
Note that Spring Boot will auto-configure both low and high level REST
clients, but since the high level one is using the former, a single
health indicator will cover both cases.
See gh-15211
