[THORN-2496] modernize the Thorntail generator

Ladicek commented 5 years ago

This commit modernizes the Thorntail generator all around the place. Specifically:

The application itself is no longer built on an outdated version of WildFly Swarm, but on latest Thorntail.
It is possible to specify the version string of the generated application, as well as an explicit package name instead of the combination of groupId and artifactId. None of that is mandatory; if missing, the original behavior is retained.
It is also possible to specify that the generated archive should not contain a top-level directory, but directly the generated application. This is off by default to preserve original behavior. It is added for the purpose of Halkyon, which expects this flat (non-nested) style of archives.
Few other tiny improvements and cleanups.

I wonder where the generator is hosted. @gastaldi I think you've been running it somewhere?

Hm, I have no idea either. I think @bobmcwhirter hosts it in a dedicated server somewhere?

Ah, OK, thanks! I'll ask.
