Previously, Maven's default behaviour was relied up which resulted
in the artifact ID being appended to each URL as it was inherited.
This behaviour can only be disabled in Maven 3.6 and later, a version
that we cannot use due to an incompatibility with the Flatten Plugin.

This commit works around Maven's default behaviour by defining
properties for the SCM URL, connection, and developer connection and
then explicitly defining the settings in each pom using these
properties. The explicit definition of the properties in each pom
prevents them being inherited from the parent, thereby disabling the
unwanted appending of the artifact ID to the URL.

Fixes gh-18328

Update `JerseyManagementContextConfiguration` so that customizer beans
are not longer applied. The endpoint resource endpoints are now added
with a registrar bean `@PostConstruct` method.

Prior to this commit, when running the management server on a different
port a `Resource` added by a customizer could be added two different
`ResourceConfig` instance. This breaks the singleton contract expected
by Jersey.

  Apply TTL invocation caching on reactor types

Closes gh-18339

Extract reactor specific code to an inner class to protect
against ClassNotFound exceptions if reactor is not in use.

Also add support for `Flux`.

See gh-18339

Update `CachingOperationInvoker` so that TTL caching is applied directly
to reactive types. Prior to this commit, a `Mono` would be cached, but
the values that it emitted would not.
