Update `MetricsEndpoint` so that only the first matching meter is used
when calculating the sum of of statistics.
Prior this this commit the endpoint would consider all Meters. This
caused incorrect statistics when multiple back-end systems were being
used since the registries contained in the `CompositeMeterRegistry`
would be iterated, and the same effective metric would be counted more
than once.

Previously, if the call to connection.start() hung, JmsHealthIndicator
would also hang and then never respond.
This commit introduces the use of an additional thread that waits for
up to 5 seconds for the connection to start. If the call to start
does not complete within that time, the connection is closed. The
call to close causes the call to start to throw an exception, thereby
stopping the hang and allowing the indicator to report that the
broker is down.

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.

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.
