This patch moves (as discussed at the Newton design summit) the
s3_token middleware from keystonemiddleware to swift3. The git
history is not included based upon the agreement between the
Keystone team and the Swift3 team.
This is based on s3_token.py from openstack/keystonemiddleware@234913e
Note that the egg entrypoint has changed from "s3_token" to "s3token"
for consistency between entrypoint and recommended pipeline names.
Additionally, keystone functional tests now use the in-tree s3token
middleware.
Upgrade Impact
==============
Deployers currently using keystone for authentication should change
their s3token filter definition to use the middleware provided by swift3
rather than the one provided by keystonemiddleware. Note that
keystonemiddleware will still need to be installed, and its auth_token
middleware configured.
