initial dockerization commit.

[pdion891]

Initial PR for Dockerization of CloudStack.

Important Changes:

• scripts/vm/systemvm/injectkeys.sh: script execution will pass event if /dev/loop0 not detected and will skip verification of sshkey, this is a limiation in Docker container.
• Dockerfile for simulator move into /tools/docker: Need to change Jenkins jobs and Dockerhub build after the merge.

Current docker file working:

• simulator (Seb's original file)
• management-server on centos6 (using RPM's)
• marvin

comments from PR #605 corrected.

Hello dev@!

I'm looking for another LGTM (real one, please read the PR) as replacement
of Seb, PR #623 replace the PR #605 based on Seb's comments.

Cheers,

I was able to build the images locally. changes looks good. 👍

for the centos 6 and marvin, it is always taking 4.6 images from jenkins. Which means we have to change this file for every release. Is there a way to get the current working release and probably release -1? If we could tag the master as latest and release-1 with the release number, that would be great.

@karuturi , I haven't found a way to specify the release number at the docker build. If there is a way I would use it so Dockerfiles would be same across branches.
