images.update() fails when image contains multiple tags

[Julien Vey]

When updating an image which contains multiple tags, glanceclient create the following request body for the PATCH method

'[{"path": "/tags/0", "value": "tag1", "op": "replace"},
{"path": "/tags/1", "value": "tag2", "op": "add"},
{"path": "/tags/2", "value": "tag3", "op": "add"}'),

This results in a 400 Bad Request "Invalid JSON pointer for this resource: '/tags/0'"

According to http://docs.openstack.org/api/openstack-image-service/2.0/content/update-an-image.html It should create the following, to be understood by the API

[{"path": "/tags", "value": ["tag1", "tag2", "tag3"], "op": "replace"}]'

    Apply expected patch format when updating tags in v2.images

    Currently, glanceclient.v2.update builds a patch request that does not
    match glance API.

    This patch overrides the default behaviour to customize the patch
    request with the right format for the API.
