Moves project build to ASF infrastructure

[codefromthecrypt]

This moves off non-ASF things including repositories, deployment
processes, license headers etc. It creates the same changes done
in brave-karaf. Later, we'll need to setup Jenkins to look at this
and also do a test release.

See #15

Great one, @adriancole !

I looked and this isn't producing the DEPENDENCIES file

Cool stuff. Keep in mind, once merged, we'll still need to click on the Jenkins UI to create a multi-branch pipeline job to pick up the Jenkinsfile (copying from brave-karaf should give us almost exactly what we need). Once we're up to ~5 builds, it might make sense to set up some DRY (many ways of doing that, best choice will likely come down to ASF-Jenkins plugins and permissions)

moving on despite the DEPENDENCIES issue as that also exists in karaf so we can fix them together at some point #18
