docker image should shut down faster when there's no active connections

[lmsurpre]

Is your feature request related to a problem? Please describe. When you sent SIGINT to liberty (e.g. by asking the container to stop) it has a quiesce period that is 30s by default. But if there's nothing happening, it should shut down sooner.

Unfortunately, in our container, this never seems to happen.

Acceptance Criteria

1. GIVEN a running ibm-fhir-server container (use -i and -t unless we fix #3565) AND its not processing any requests WHEN you interupt the process (e.g. via control+c) THEN it should shut down right away (e.g. within 2 seconds)

Additional context

plan: issue a kill and ask java to leave a dump, then see what threads are running.

• kafka? azure? batch? something else?

[lmsurpre]

note: shutdown happens immediately if the server hasn't serviced any requests yet. but i just ran an experiment where we issues a GET /metadata and then a couple requests that errored out...after that it took the full 30 seconds to shut down.
