Remove version from href, incorrect RE

[Alex Meade]

in nova/api/openstack/common.py

the remove_version_from_href function currently uses the RE:

new_href = re.sub(r'[/][v][0-9]*.[0-9]*', '', href)

this incorrectly handles any href with a "/v" in it
it should be:

new_href = re.sub(r'[/][v][0-9]+\.[0-9]+[/]', '/', href)
or
new_href = re.sub(r'[/][v][0-9]+\.[0-9]+', '', href)
depending if the href ends in '/'

If a version appears more than once in the href (would that ever happen?), I'm assuming this function should remove only the first occurrence. Please let me know if that's not the case.
