    Bug 929021.

    Monitor ready node count for all providers.

    * devstack-vm-threshold.py
    New script to print count of available nodes, across all providers.
    The threshold is specified in command line. If available node count
    is less than threshold, the script exit with error code (1).

    The available node count is written to a file. File name is
    specified in command line. If file name is not specified, it is
    written to ~/vm-threshold.txt file.

    usage: devstack-vm-threshold.py [-h] -t threshold [-f stat-file]
