Port jenkins jobs from jenkins.hosts.mwqe.eng.bos.redhat.com to central CI

Currently several productisation tasks rely on older infrastructure, these jobs would most likely see a speed improvement by being moved to central CI with other fuse Jenkins jobs.

The existing jobs are

Link:
https://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/fuse-offline-repo-gen-6.3/

Description:
Generates the fuse "style" offline repo, takes a SCM revision of our
prod ip-configuration repo, using a config file from within it produces
a meta repository and then downloads the artifacts from a brew NFS mount
a 7GB zip with everything used and built is produced

Link:
https://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/fuse-offline-repo-gen-6.3-mrrc/

Description:
Same as about but produces a ~3GB zip file which should be built
artifacts only destined for the MRRC.

Description:
Same as above but for Fuse 6.2.x

Link:
https://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/release-generation/

Description:
This job is similar to the others in that it again uses the brew/koji
client to build and download a bunch of artifacts, the only difference
it also has a persistent couchdb service associated with it to keep a
track of all our built and released artifacts.
