The Keystone audit test flips the "enable-telemetry-notifications"
setting to ensure that the audit messages are emitted with
and without telemetry notifications enabled.
As a result, Keystone gets restarted twice and it can take
a while for the service to recover, see the following bug:
https://bugs.launchpad.net/sunbeam-charms/+bug/2114836
We're getting Keystone 503 errors, despite the fact that the
unit is reported as ready.
To mitigate this and avoid test flakes, we'll simplify the
test and avoid changing this charm setting.
