Inconsistency in the installation of openstack clients

[Tom Howley]

When installing from source, openstack clients will be installed in two different ways:
- In openstack-clients element, each client is installed from the cloned source repos specific in that element.
- In os-svc-install element, the clients are pip installed (when included in the requirements).

So you will end up with a deploy with different versions of openstack clients in different venvs. For example, if you are using a common env and a nova env, you could have different glance clients installed in both.

On potential interim solution is to allow for the install of clients off source repos within bin/os-svc-install (prior to pip install of the requirements).

This is an oddity, but I don't see it as a high severity problem. The projects involved are gated on pip-released clients, so either install source should work fine. It would be nice to eliminate the inconsistency, but AFAICT it shouldn't cause any problems as it is now.

    Install os clients from git

    When installing openstack clients, which have been pulled in as
    requirements for openstack services, allow for the installation
    from source repos, if the source install type has been selected.
