congress does not respect devstack branch

[Tim Hinrichs]

To run all the openstack projects for a given branch B such as stable/liberty, you simply do a git-checkout -b B within devstack before running stack.sh. This causes devstack to run git clone ... -b B for every project it installs.

When following the devstack install instructions for Congress but cloning devstack with -b B, the B branch is not checked out for Congress; instead master is checked out.

I suspect devstack provides the B branch as an environmental variable (or something similar), and the congress contrib/devstack scripts do not properly deal with that variable.

It seems we are using the CONGRESS_BRANCH as we should be doing. But it seems it doesn't get properly set.

I'm told on #openstack-infra that the gate will do the proper thing, so mainly this is a problem for end users trying to check out the stable/liberty branch via devstack.

I tried setting CONGRESS_BRANCH to DEVSTACK_BRANCH, but no luck

I added a release note in case we can't fix the problem.

It seems that we're being forced to create a devstack plugin for the next release since the copy/paste version will no longer be supported.

    Fix use of devstack-based branch for congress

    Devstack uses the github URL provided in local.conf.
    Doing stack.sh does checkout the relevant branch.
    plugin.sh need not explicitly checkout the branch. The plugin can
    install only the congressclient and any other dependencies
    (like java-jre) from the script.
    Also adding a README.rst for enabling the plugin for devstack.
