In the past, we only grabbed the tenant ID out of the uri, and we knew where to look for the tenant ID by using the uri-extraction-regex attribute in the Keystone filter's config. Now, we have a whole filter to take care of it, and the Keystone filter only needs to know which header to look at to determine what the tenant ID of the request is.
We should remove the deprecated uri-extraction-regex attribute since it is extraneous now.
- The uri-extraction-regex attribute is removed from Keystone's configuration options.
- The Upgrade Guide is upgraded with a detailed list of changes that can be made to re-create the old config (i.e. by using the URL Extractor to Header Filter).
