metadef tags create api does not match blue-print

[Wayne]

The blueprint for metadef tags shows:
Create / Replace all tags in a specific namespace
    POST /metadefs/namespaces/{namespace}/tags/
and
Add tag in a specific namespace:
    POST /metadefs/namespaces/{namespace}/tags/{tag}

Unfortunately, these were implemented as:
Create / Replace all tags in a specific namespace
    PUT /metadefs/namespaces/{namespace}/tags/
and
    POST /metadefs/namespaces/{namespace}/tags/

This bug seeks to rectify this situation and use the correct action/URI.
Even though the metadef tag library has been checked in, the associated python-glanceclient check in has not been approved yet. Additionally, the specs for the metadef tag changes have not been posted anywhere yet, so, hopefully this can be changed with minimal impact.
