This PR was created on top of #242, and should be merged after that.

This change includes what was previously covered by #242: Refactoring of all DB container tests into a single separate module. The idea is that this will make it easier to reduce duplication between tests in the future. Along the way, some reliability issues with DB containers have been worked on:

This also goes through a few places where unnecessary stack traces or errors were indicated during tests. It emerged that some behaviour (container reaper and exec-based liveness checks) were running against stopped or deleted containers, causing loud error logging from docker-java.

Actually even though it's a little brittle I'd prefer to keep it that way. If stopContainer fails for some reason, my feeling is that it's slightly better to potentially try again by leaving the containerId in the registered set.

…r refactoring of common elements.

Adopt MySQL and MariaDB default configuration with lighter resource requirements
…o enable them to be volume mounted into containers.
…path resources that have been extracted from JAR files.
* ensure that liveness `exec` calls don't fire when a container is not running
* check that containers exist before trying to clean up in ResourceReaper
* filter out common ANSI control code in stderr output
* amend frame consumer result callback to suppress errors
