    Add CRUD methods for tags to the EC2 API.
    
    This is an incomplete implementation of the EC2 tags API.  In EC2, most
    resources are able to be tagged.  See
    http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html
    
    In openstack, the only currently 'taggable' resource is an instance, as
    it has an instance_metadata table associated.  So far, only instance
    tagging has been implemented, but it is relatively simple to extend this
    to other resource types by creating the associated model and api calls.
    
    Additionally, in EC2 searches, shell-style globs are allowed, eg:
    fo* will match fo, foo, foobar
    fo? will match foo
    
    This has been left to do at a later date.
