The e2e/acl package has some nice helpers for tracking and cleaning up ACL
objects, but they are currently private. Export them so I can abuse them in
other e2e tests.
The NSD checks tests were racey, whereby the check may not have
been triggered by the time it was queried. This change wraps the
check so it can account for this.
This removes the current ACL expiration GC section in order to get
the tests passing and allow more time to investigate the test. I
have full confidence the feature is working as expected and have
tested extensively locally.
In order to add an E2E test to cover token expiration, the server
config has been updated to include a low minimum allowed TTL
value. For ease of reading, the max value is also set.
