ethan / HR-midPoint-Grouper-Wordpress-Demo

Sometimes we are trying to pull an image that is not pushed yet.

(This one is not currently used anyway.)

This also changes HTTPS ports mappings (Shibboleth IdP is now on 443,
Grouper on 4443, midPoint remains on 8443).

(because of MariaDB changes)

(needs MariaDB support of extra SQL scripts i.e. PR #8-11 to work)

Plus a couple of other fixes in library.bash.

A couple of Grouper-related tests were added, including testing
of live sync using RabbitMQ (not finished yet).

And add the code to create sampleQueue on the first run.

Created a special version of docker-compose files that do not expose
any ports unless really needed for test execution. This is to minimize
potential conflicts during test execution.

We have to build the composed containers because the Dockerfiles
might be updated (as they are now).

Plus a couple of minor fixes.

(i.e. the final cleanup)

Changes are in the naming of containers and secrets;
some environment variables were changed as well.
