  Add missing spring-data-cassandra metadata

This commit adds the missing
`spring.data.cassandra.repositories.enabled` in the metadata and the
documentation.

This commit makes sure that if a `javax.cache.CacheManager` is required,
an auto-configured `HazelcastInstance` is fully resolved first. This
prevents the case where the JCache bootstrap actually starts an instance
early, followed by a second (potentially unwanted) instance created by the
regular auto-configuration.

Since the JCache implementation works with an `HazelcastInstance` behind
the scenes, if there is one `HazelcastInstance` configured and it has a
name, then we configure the `CacheProvider` to use that. Future Hazelcast
version will allow to pass the instance directly (i.e. not requiring an
actual name).

The changes made for gh-8299 attempted to make static resource
handling consistent across Jetty, Tomcat, and Undertow. They did so
for application's launched using JarLauncher or WarLauncher but did
not consider application's launched in an IDE or using spring-boot:run
in Maven or bootRun in Gradle.

Running in an IDE or via Maven or Gradle introduces two new
resource locations:

 - Jars on the classpath with file protocol URLs (they are always
   jar protocol URLs when using either launcher)
 - Directories on the classpath from a project that is depended upon
   and contains resources in META-INF/resources

This commit updates the factories for all three containers to handle
these new resources locations. The integration tests have also been
updated.

The NamePatternEnvironmentFilter used to throw an exception if
placeholders in property values could not be resolved.

Fixes gh-8510

This commit flags the two `BeanPostProcessors` registered by the
embedded support as `synthetic` so that they don't trigger an early
initialization of other components.

* pr/8227:
  Refine engine counter logic
  Polish web containers stop contribution
  Ensure web containers are stopped after close

Update counter logic to prevent negative values. Since the stop method
can now be called more than once, it was possible for the counter to
move into negative values.

See gh-8227

See gh-8227

Update `EmbeddedServletContainer` implementations to ensure that stop
can be called even if start has not. This allows servers that are
partially started during `initialize()` to still be shut down.

This commit fixes a regression caused by commit 0af53b36.

Fixes gh-8224
Closes gh-8227

Update `HealthMvcEndpoint` to respect `ManagementServerProperties`
roles. Prior to this commit the `HealthMvcEndpoint` directly loaded
roles rather than using bound properties. This meant that list values
from yaml were not respected.

Fixes gh-8314

Update DataSourceInitializedPublisher to always attempt to obtain the
published DataSource directly from the EntityManager. In the case where
the EntityManager doesn't provide a DataSource, the previous logic is
used.
