Revert "Switch fernet to be the default token provider"
This reverts commit 181588b9ba50fefea12617a9a5e774daddfed20c.
Since this change landed on 4/29 it's been the cause of the
top two gate failures (besides known latent infra issues) and
hasn't had good progress on landing a fix, so until it's a
priority for the keystone team we need to revert this change
to get the integrated gate jobs moving again.
