    Add db api layer for CRUD operations on node tags

    - set/unset node tags
    - get node tags
    - add/delete single tag
    - check whether node tag exists
    - Delete all tags attached to the node when it's destroyed

    This will not support creating node with tags, just ignore
    the specified tags.
