* gh-12287:
  Polish "Remove redundant auto-configuration of SI Micrometer metrics"
  Remove redundant auto-configuration of SI Micrometer metrics

Closes gh-12287

Spring Integration no longer requires a `MicrometerMetricsFactory` to
support Micrometer metrics so there's nothing for Boot to
auto-configure.

See gh-12287

Closes gh-12286

Fixes gh-12267

* pr/12284:
  Remove an unnecessary method in EndpointDiscoverer

Closes gh-12284

Prior to this commit, the `ApplicationContext` couldn't start with a
JDK-proxied `HikariDataSource` as the JMX auto-configuration was
attempting to inject a (too narrowed) `HikariDataSource`.

This commit rather injects a regular `DataSource` and attempt to unwrap
it as a `HikariDataSource`.

  Add Netty Compression support

Closes gh-12268

Reactor Netty 0.7.5 now supports all Compression options.
Unlike previous Reactor Netty versions, the minimum compression
threshold is now based on the content-length instead of
accumulating for a while the data.

Closes gh-12233

Update `EndpointRequest` to that the `PathMappedEndpoints` bean is
optional. A missing bean is treated as if there are no path mapped
endpoints.

Fixes gh-12238

Update `WebMvcTypeExcludeFilter` to include `WebSecurityConfigurer`
beans.

Fixes gh-12275

Fix test failing due to commit d6649678.
