Move jetty maven plugin integration tests out to tests module

jetty-12

We should move the integration tests for the jetty maven plugin out of each of the jetty-eeX-maven-plugin subprojects, and move it into submodules of tests instead. This will solve a nasty circular dependency, where the plugin integration tests depend on jetty-home (which in turn depends on each of the eeX subprojects).

@olamy any comments?

My comment is a nasty circular dependency this is not nasty nor circular but a real dependency :)
To be honest, I think it's a lot of work for minor/none improvement. I would not even see this as a improvement as it will move some test files in another place of the source tree of the maven plugins code and by the way every maven plugins test will still have dependency on jetty-home.
And with the cache, the build is really fast now when testing this locally or via PR.
So, personally, I would not change that.

@olamy there is a circularity via the various eex-home modules: jetty-eex-maven-plugin -> jetty-home -> jetty-eex-home -> jetty-eex-maven-plugin.
My other thought is that we have the tests/test-integration module where we do all kinds of integration tests, so why not the plugin too?

I cannot see such dependency jetty-eex-home -> jetty-eex-maven-plugin. (from here https://github.com/jetty/jetty.project/blob/e1c7a7ca02a913b7def99af8223ad4e2855425a6/jetty-ee10/jetty-ee10-home/pom.xml)

If you want to do it for consistency, just do it. I just find it extra work for no gain but those new modules will still need dependency on jetty-home and so when we will want to test any change with maven plugins the build (up to jetty-home will be the same)
