Allow Multiple Filters of the Same Key

Before, the way filters were passed in would not allow filtering
on the same key.
For example:
    keystone.users.list(name__contains='test', name__contains='user')
This fails because of how kwargs handles key/value pairs.

This patch allows using multiple values for the same filter.
Example:
    keystone.users.list(name__contains=['test', 'user'])
Specifying the only one filter value is still functional as expected.
