Deprecate credential config options
This commit deprecates the original configuration options for
providing credentials. This mechanism of providing tempest with
credentials to run with has a lot of drawbacks and has been
superseded by using an accounts.yaml file. It has been planned
for deprecation once we had a periodic/experimental CI job setup
to run with test accounts enabled. Now that this has been done
we can start the deprecation cycle for the old options.
