Merge lp:~soren/nova/version into lp:~hudson-openstack/nova/trunk

[Soren Hansen]

Adds a mechanism to programmatically determine the version of Nova. The designated version is defined in nova/version.py. When running python setup.py from a bzr checkout, information about the bzr branch is put into nova/vcsversion.py which is conditionally imported in nova/version.py.

In short, you can now do:

>>> import nova.version
>>> nova.version.canonical_version_string()
'2011.1'
>>> nova.version.version_string()
'2011.1-dev'
>>> nova.version.version_string_with_vcs()
u'2011.1-newlog2:<email address hidden>'

It's also consumed by the docs and setup.py, so this ought to be the canonical place for updating version information from now on.

nova/version.py is missing a copyright header.

Good catch, Eric. Fixed. Thanks!

The attempt to merge lp:~soren/nova/version into lp:nova failed. Below is the output from the failed tests.

There we go. I decided last second to change the function names, didn't follow through. Should be fine now.
