Note that it is NOT enabled by default, which should be OK for the ASF.
The main point here is just to clearly document it for end-users.
I've obviously tried out what's documented, and can confirm it works.
This speeds up e.g. "podman-compose build" for me from 5m to 4m.

In Docker, set JAVA_OPTS instead of FINERACT_TENANTS_URL.
Because ARG/ENV in the Dockerfile can't (easily) be changed at run-time.
At first I tried to override the ENTRYPOINT with a script which sets
JAVA_OPTS based on FINERACT_TENANTS_URL and then delegates to the original
/app-entrypoint.sh; that didn't immediately work, so this seems simpler.
Including make default tenant JDBC hostname & port configurable at Docker container run instead of build time.
Now that we separated the build and runtime containers,
we can have only a JRE but not a JDK in the runtime container
(whereas the builder container will still have a JRE).
This makes for a smaller, and more importantly,
more secure, runtime container image.
Also removing git from runtime container, as it's not used.
we (of course), still, but only, run it in-App at runtime boot
This is a clean-up which removes something we don't actually need.
Most importantly, it unblocks the Gradle upgrade in FINERACT-700,
where this doesn't work anymore anyway (and while there's a fix
making it work on one of my branches, it seems simpler to just
remove it).
