Previously, if WebFlux and Jersey were on the classpath, but there was
no Servlet API (and no embedded container) on the classpath, the web
application type would be prevented from being reactive. The absence
of the Servlet API would then prevent the web application type from
being servlet so it would be none.
By contrast, if Spring MVC was on the classpath in place of Jersey
the absence of the Servlet API would allow the web application type to
be reactive. This happened because the Spring MVC indicator class is
DispatcherServlet which requires the Servlet API.
This commit updates the Jersey indicator class to be ServletContainer.
This class is both an HttpServlet and a Filter so it too requires the
Servlet API and, therefore, further aligns the deduction behaviour for
Jersey and Spring MVC.

Rework Prometheus push gateway support so that the central class can
be used outside of auto-configuration. The shutdown flags have also
been replaced with a single "shutdown-operation" property since it's
unlikely that both "push" and "delete" will be required.
It's also possible now to supply a `TaskScheduler` to the manager.

Update `DevToolsPropertyDefaultsPostProcessor` to automatically set
the recently introduced `spring.messages.reloadable` property to
`true`.

Previously, the JSON-B auto-configuration would be enabled when the JSON-B API was
on the classpath. This led to a failure if there was no implementation available.
The JSON-B API loads an implementation using the service loader. This commit updates
the auto-configuration to be conditional on the presence of a
META-INF/services/javax.json.bind.spi.JsonbProvider file on the classpath.
Closes gh-14675
Add a `spring.messages.reloadable` configuration property which can be
used to auto-configure a `ReloadableResourceBundleMessageSource` rather
than a `ResourceBundleMessageSource`.
Closes gh-13377
