containers need a system to define a bootstrap node

[Michele Baldessari]

Today in docker/services/keystone.yaml we do the following:
....
          keystone_bootstrap:
            start_order: 2
            action: exec
            command:
              [ 'keystone', 'keystone-manage', 'bootstrap', '--bootstrap-password', {get_param: AdminPassword} ]
....

When deploying on multiple controllers this will break. We need a way to make sure that this runs only on the first container for the service. We were trying to test if something like the following could work:
if [[ "$(hiera -c /etc/puppet/hiera.yaml keystone_short_bootstrap_node_name)" == "$(facter hostname)" ]] ; then ...do bootstrap stuff...; fi

But at least in the keystone_bootstrap container this is not currently possible because there is no hiera. Or we try to use only puppet for this?

It seems related to approaching DB sync the same way https://bugs.launchpad.net/tripleo/+bug/1677652

    Add a bootstrap_host_exec CMD

    Adds a simple command line utility that will exist in all TripleO
    containers (we may need this in a variety of places) so that we
    can quickly figure out whether a command should execute on the
    bootstrap node (or not).

    For example:
      ./bootstrap_host_exec heat_engine heat-manage db_sync

    would only execute the DB sync for heat on the bootstrap node.
    Internally the script uses hieradata to determine when to run the
    supplied command.

    Also, adds openstack-tripleo-common to the base container image so we
    can use it in a variety of container images.

    docker bootstrap service commands

    This patch guards db syncs and initialization code from executing
    on multiple nodes at the same time by using the new
    bootstrap_host_exec script. This helper script checks to make
    sure the container is executing on the "bootstrap host" for the
    specified service (arg 0) and then if it matches runs the
    specified command.
