Flavio Percoco 00d5f56a33 Show team and repo badges on README
This patch adds the team's and repository's badges to the README file.
The motivation behind this is to communicate the project status and
features at first glance.

This is a client for the OpenStack Nova API. There's a Python API (the
``novaclient`` module), and a command-line script (``nova``). Each
implements 100% of the OpenStack Nova API.
See the `OpenStack CLI guide`_ for information on how to use the ``nova``
command-line tool. You may also want to look at the
`OpenStack API documentation`_.

Command-line API
----------------
Installing this package gets you a shell command, ``nova``, that you
can use to interact with any OpenStack cloud.
You'll need to provide your OpenStack username and password. You can do this
with the ``--os-username``, ``--os-password`` and ``--os-project-name``
params, but it's easier to just set them as environment variables::
export OS_USERNAME=<username>
export OS_PASSWORD=<password>
export OS_PROJECT_NAME=<project-name>
You will also need to define the authentication url with ``--os-auth-url``
and the version of the API with ``--os-compute-api-version``. Or set them as
environment variables as well and set the OS_AUTH_URL to the keystone endpoint::
export OS_AUTH_URL=http://<url-to-openstack-keystone>:5000/v3/
export OS_COMPUTE_API_VERSION=2.1
Since Keystone can return multiple regions in the Service Catalog, you
can specify the one you want with ``--os-region-name`` (or
``export OS_REGION_NAME``). It defaults to the first in the list returned.
You'll find complete documentation on the shell by running
``nova help``
Python API
----------
There's also a complete Python API, with documentation linked below.
To use with keystone as the authentication system::
>>> from keystoneauth1.identity import v3
>>> from keystoneauth1 import session
>>> from novaclient import client
>>> auth = v3.Password(auth_url='http://example.com:5000/v3',
... username='username',
... password='password',
... project_name='project-name',
... user_domain_id='default',
... project_domain_id='default')
>>> sess = session.Session(auth=auth)
>>> nova = client.Client("2.1", session=sess)
>>> nova.flavors.list()
[...]
>>> nova.servers.list()
[...]
>>> nova.keypairs.list()
[...]
Testing
-------
There are multiple test targets that can be run to validate the code.
* tox -e pep8 - style guidelines enforcement
* tox -e py27 - traditional unit testing
* tox -e functional - live functional testing against an existing
openstack
Functional testing assumes the existence of a `clouds.yaml` file as supported
by `os-client-config` (http://docs.openstack.org/developer/os-client-config)
It assumes the existence of a cloud named `devstack` that behaves like a normal
devstack installation with a demo and an admin user/tenant - or clouds named
`functional_admin` and `functional_nonadmin`.
