Glance metadata definitions requires v2 API

[Justin Pomeroy]

The "Update Metadata" actions for images, flavors, etc. currently fetches the metadata definitions from glance to display in the metadata modal. The metadata definitions API was introduced with the v2 API and if this is not being used the user will get an error.

"Error: Unable to retrieve the namespaces"

To replicate, edit the file /etc/glance/glance-api.conf and set the following:

    enable_v1_api = true
    enable_v2_api = false

Then restart glance API.

    Add version check for listing namespaces

    Listing metadata definitions namespaces requires glance API version
    2. This adds a check that makes sure an empty array is returned if
    any version less than 2 is being used.
