An update!
The followup was very productive, the upstream OCF RAs merge plan is

1. The rabbitmq-server repo [0] will be the destination for the merged
OCF RA.
2. Fork it [1] for the merge process and enable a travis CI check for
incoming pull requests. Note that the check exists upstream as well but
has yet to be enabled properly. Also, we decided to run tests for *only*
a cluster assembled with the merged OCF RA, w/o other components like
OpenStack or DB cluster.
3. Update the travis CI check (see example job script [2]) to meet use
cases of the 2nd OCF RA, from the resource-agents repo, we want to merge
with. So the test case shall benefit all sides of the merge process.
4. Start submitting patches to the merged RA.
5. Once finished, submit it to the upstream source at step #1. Or do it
by every (stable) patch based as well.

Action items:
* Peter Lemenkov (petro) to try a dev env via vagrant scripts [3] as
well as check it against the (RHOS/resource-agents?) packages containing
the 2nd upstream OCF RA.
* Oyvind Albrigtsen (e-ddie) to investigate ASL/GPL licensing questions.
Hopefully no issues expected and the merged OCF RA should be licensed
with ASL v2.0.
* Bogdan Dobrelya (bogdando) to investigate destructive test cases for
the travis CI check as well. The plan is to use custom jepsen tests [4]
for that.

An update item #2:
I created the aforementioned jepsen test [4], to test a rabbit cluster
recovery after network partitions. The travis CI check may run it now as
well [5], although faily a little - It may time out, but works well for
my dev box :) How-to use can be found in the README [3].
