  Polish "Stop MetricsEndpoint from summing up same metrics"
  Stop MetricsEndpoint from summing up same metrics

See gh-14497

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.
