    Revert "Remove all usage of keystoneclient"

    This reverts commit 810417df865c7b4eb71cee4dfee843d65972852b.

    The Swift driver not being able to use Trusts had nothing to do
    about the store driver itself nor that keystoneauth1 would have
    broken the feature, but rather it not having the functionality
    in the first place and us not catching that on reviews.

    We should figure out how to test this before we try to replace
    this code again.

    merge-conflict on requirements jsonschema.
