  - Merge "Allow flexible openstack jobs"
  - Allow flexible openstack jobs

    The current openstack CSIT always assumes a 2 node deployment
    composed of one control node and two compute nodes.
    This should be flexible and allow the following combinations:

    cmb: combined control+compute
    ctl: control
    cmp: compute

    control+compute: 1cmb-0ctl-0cmp
    control+compute and compute: 1cmb--ctl-1cmp
    control+compute and two computes: 1cmb-0ctl-2cmp
    control and one compute: 0cmb-1ctl-1cmp
    control and two computes: 0cmb-1ctl-2cmp

    This patch is the first step at just naming the jobs to reflect
    the deployment by adding the counts for the different openstack
    components as follows:

    netvirt-csit-1node-0cmb-1ctl-2cmp-openstack-queens-upstream-
    stateful-fluorine
