This commit adds support for Redis cache metrics. Users can opt-in for
statistics using the "spring.cache.redis.enable-statistics" property.
Closes gh-22701
Constructor calls like new AtomicInteger(0) cause a volatile write that
can be saved in cases where the constructor parameter is the default
value.

Previously, all MeterFilter beans were applied to all MeterRegistry
beans. As a result, when a composite registry was auto-configured, both
the composite and all of its delegates would have the same MeterFilters
applied. This made it impossible for one of the delegate registries to
have a locally-configured filter that would allow a meter that would be
denied by one of the MeterFilter beans applied to the composite.
This commit update MeterRegistryConfigurer to skips the auto-configured
composite meter registry when applying MeterFilter beans to
MeterRegistry beans. As a result, the composite's filters will no
longer deny a meter before it reaches a delegate that would have
accepted it due to one of its locally-configured filters.
Closes gh-23381
With the introduction of health indicators that only require the
CqlSession, this commit deprecates the health indicators that require
Spring Data since the latter build on top of the former.
Closes gh-23226
Prior to this commit, Spring Boot would auto-configure both
Elasticsearch variants: `RestClient` ("Low Level" client) and
`RestHighLevelClient` ("High Level" client).
Since one can be derived from the other, this would create complex and
unclear situations depending on what developers provided with their
configuration.
`RestHighLevelClient` is mostly for actual use of the Elasticsearch API,
with support for specific methods and (de)serialization. On the other
hand, `RestClient` is merely wrapping the Apache HTTP client for
load-balancing support and low level HTTP features.
This commit completely removes the support for `RestClient` in Spring
Boot and now requires the presence of the
`org.elasticsearch.client:elasticsearch-rest-high-level-client`
dependency for REST client support with Elasticsearch.
Closes gh-22358
This commit builds on top of gh-22603 and exposes data collected by the
`BufferingApplicationStartup` on a dedicated `"/startup"` Actuator
endpoint.
Closes gh-23213
Rename `CompositeMeterRegistryAutoConfiguration` to
`MeterRegistryAutoConfiguration` since it can also create non-composite
registries.
Closes gh-22988
Update metrics auto-configurations so that they are auto-configured
after `CompositeMeterRegistryAutoConfiguration` in order to ensure
the `MeterRegistry` bean has been defined.
Prior to this commit, metrics auto-configurations that depended on a
`MeterRegistry` has `@AutoConfigureAfter(MetricsAutoConfiguration.class)`
which is not sufficient since `MetricsAutoConfiguration` does not export
a `MeterRegistry`.
