    Automatically generate vmware-nsx configuration files

    This patch adds support to automatically generate config files
    for vmware-nsx repo using oslo config generator[1] for all
    VMware plugins.
    Tox can be used to generate a sample config file using the
    following command:
        tox -e genconfig
    This will generate a config file "nsx.ini.sample" under
    vmware-nsx/etc/ folder.

    This patch also modifies devstack scripts to use the
    auto-generated config files and adds more information to help
    texts in config modules.

    This patch is a follow up to the auto generate config file patch[1]
    which removes the static example nsx.ini file from the repo as
    it is now redundant.
