devstack env LIBS_FROM_GIT not supported

[Peter Stachowski]

devstack has changed recently to install clients from Pypi instead of from Git. This means that on a clean redstack install you will not be running the latest clients, and any changes to clients will not be reflected in CLI testing.

The LIBS_FROM_GIT should be set by default to the list of clients typically used by Trove developers.

Note: This only affects brand new installs on new machines. Older machines will already have the necessary links in place.

    Support new devstack LIBS_FROM_GIT env variable

    devstack has changed recently to install clients from Pypi instead of
    from Git. See:

    https://github.com/openstack-dev/devstack/commit/cc52406a78

    This means that on a clean redstack install you will not be running the
    latest clients by default, and any changes made to client code will not
    be reflected in CLI testing.

    The LIBS_FROM_GIT has been set to the list of common clients. Namely:
        python-troveclient

        python-ceilometerclient
        python-cinderclient
        python-glanceclient
        python-heatclient
        python-keystoneclient
        python-neutronclient
        python-novaclient
        python-openstackclient
        python-saharaclient
        python-swiftclient

    The following oslo libraries have also been included:
        cliff
        cookiecutter
        oslo.concurrency
        oslo.context
        oslo.config
        oslo-cookiecutter
        oslo.db
        oslo.i18n
        oslo.log
        oslo.messaging
        oslo.middleware
        oslo.rootwrap
        oslo.serialization
        oslosphinx
        oslotest
        oslo.utils
        oslo.version
        oslo.vmware
        pylockfile
        hacking
        pbr
        pyCADF
        stevedore
        taskflow
        tooz

    Note: This only affects brand new installs on new machines. Machines
    that have already run 'redstack install' will already have the necessary
    links in place.
