Launcher: should be moved from base to central

as discussed in https://github.com/jbosstools/jbosstools-base/pull/631#issuecomment-421092171

This should all live in central, and it shouldn't really be added to the common.all feature if we intend to simply move it later.

Give it it's own feature, add it to the master list of features added to the project, and then later move it to the central repo.

I personally believe a rename-and-move is just fine even before a Final. Keeping it where it is through a final actually is what's harder to change. Then it becomes a sort of API that the common.all feature contains this launcher, and later it won't.

we should move the launcher from jbosstools-base to jbosstools-central
