Support for JIB(Java Image Builder) mode in dmp

[rohanKanojia]

This ports Jib support added in Eclipse JKube in eclipse-jkube/jkube#257

Thanks a lot, @rohanKanojia ! That's awesome ;-)

Unfortunately I'm on the road this week, so probably can't review it this week.

One thing I remarked is that docker:build with JIB pushes to a registry like docker:push would do. I know that's how JIB works normally, but maybe we can still keep that phases seperate ? I.e. docker:build would create the tar file only and docker:push would move it to the registry ?

[rohanKanojia]

@rhuss : Yes, I think this is possible and I would also like to have behavior like this. JIB has an offline mode; we can force offline mode during build phase and regular build during push phase.

@rohanKanojia Thanks a lot, looks good ! Let me integrate it until the end of the week, when I'm back from the conference.

This has some problems, marking as WIP until update.

@rohanKanojia ok, let me know when its ready for review.

[rohanKanojia]

Actually, we faced some issue on fmp for this jib, jibservice wasn't considering some parameters of ImageConfiguration . I have refactored code a bit to handle those cases(for ex, when you want to push a registry other than docker hub). But you're the expert here, you can put more light on what other use cases are still missing during code review.

I will review this PR after the next release. But let's get out a version of dmp first, as it already contains a tons of new stuff.

@rohanKanojia sorry for the delay, but could you rebase this and fix the conflicts ? Let's get this in for the next release ...

Thanks ! Looks good to me on a quick review. Let's merge the PR now and we always can refine it later if needed.
