SERVER - view tags in post details

[egeehartz]

http://localhost:8000/tags?post_id=1 needs to return tags

THEREFORE

in views/tag.py
update def list with something like this (?)

post_id = self.request.query_params.get('post_id', None)
        if post_id is not None:
            tags = tags.filter(tag_id=tag_id)
