Dean Troyer 3abfea083a Fix compute API version snafu
novaclient 2.27.0 introduced the API microversion discovery and client.Client
now wants an api_version argument to properly work out the correct API
version in use.  OSC needs to provide this when required.

Letting the compute client plugin do the version validity checking makes more
sense than encoding it into shell.py, so I've added a new OSC plugin interface
function check_api_version() that is called from shell.py if it exists.  If it
either does not exist or it returns False the previous version checking using
API_VERSIONS is still performed.

compute.client.check_api_version() conditionally imports the new
novaclient.api_versions module and uses it if successful.  Otherwise
check_api_version() returns False and the previous code path is resumed.

One side-effect of this is that it is now valid to use --os-compute-api-version
with any valid microversion supported by the installed python-novaclient.

===============
OpenStackClient
===============

OpenStackClient (aka OSC) is a command-line client for OpenStack that brings
the command set for Compute, Identity, Image, Object Store and Volume APIs
together in a single shell with a uniform command structure.

The primary goal is to provide a unified shell command structure and a common
language to describe operations in OpenStack.

Getting Started
===============

OpenStack Client can be installed from PyPI using pip::

    pip install python-openstackclient

There are a few variants on getting help.  A list of global options and supported
commands is shown with ``--help``::

   openstack --help

There is also a ``help`` command that can be used to get help text for a specific
command::

    openstack help
    openstack help server create

Configuration
=============

The CLI is configured via environment variables and command-line
options as listed in  http://docs.openstack.org/developer/python-openstackclient/authentication.html.

Authentication using username/password is most commonly used::

   export OS_AUTH_URL=<url-to-openstack-identity>
   export OS_PROJECT_NAME=<project-name>
   export OS_USERNAME=<username>
   export OS_PASSWORD=<password>  # (optional)

The corresponding command-line options look very similar::

   --os-auth-url <url>
   --os-project-name <project-name>
   --os-username <username>
   [--os-password <password>]

If a password is not provided above (in plaintext), you will be interactively
prompted to provide one securely.

Authentication may also be performed using an already-acquired token
and a URL pointing directly to the service API that presumably was acquired
from the Service Catalog::

    export OS_TOKEN=<token>
    export OS_URL=<url-to-openstack-service>

The corresponding command-line options look very similar::

    --os-token <token>
    --os-url <url-to-openstack-service>
