Add test utility to create OpenStack client container.

JIRA: MODELS-4

Installs OS clients in a docker container, avoiding the need to
create a virtualenv or install additional software on the host.
Tests and manual operations can then be invoked thru the docker API.
Fixed usage notes.

+# Status: this is a work in progress, under test.

+# How to use:
+#   $ bash osclient.sh setup|run 
+#   setup: install the OpenStack CLI clients in the container
+#     bash osclient.sh setup credential_script [branch]
+#     credential_script: OpenStack CLI env setup script (e.g. admin-openrc.sh)
+#     branch: git repo branch to install (e.g. stable/newton)
+#   run: run a command in the container
+#     bash osclient.sh run command
+#     command: command to run, in quotes
