WADL clean-up -

Some WADLs are missing the {tenant_id}, so I added it.
Some WADLs had misplaced request parameters, so I moved them.

Fix bug Image, Flavors and Image metadata api is wrong

This patch inclute {tenant_id} in some calls like:

GET v2/{tenant_id}/images Lists IDs, names, and links for ...
GET v2/{tenant_id}/images/detail Lists all details for available images.
GET v2/{tenant_id}/images/​{image_id}​ Gets details for a specified image.
DELETE v2/{tenant_id}/images/​{image_id}​ Deletes a specified image.

The same change will happen for Flavors and Image metadata.
