[KeyVault] - Update Keys and Admin to Identity 2.0 (Azure#15060)

This PR updates KV Keys and Admin to Identity 2.0.0-beta.3 and re-records all the tests as part of our team-wide effort
to migrate over.

In passing, I also re-enabled two tests that are no longer broken on the service side (hopefully) and increased the wait-for
workaround to 60 seconds when activating a Managed HSM. 30 seconds failed for me, and I'd rather avoid re-running tests
due to setup.
