[Feature/Identity] Bearer auth via internal idp

[stephen-crawford]

Description

This PR introduces bearer authentication with JWTs for feature/identity. It includes the changes introduced in #4798 because the authentication uses the same token management system to operate. There are included unit tests for bearer authentication which check catching early JWTs, expired JWTs, and valid JWTs. It is not clear what an invalid JWT would be if it were not early or expired.

There are also adaptations of the basic auth integration tests.

@DarshitChanpura @cwperks @peternied I am opening this for some feedback. The gradle check is still failing because it says a license is missing for a jar file. I am not sure what the fix for that is but if you have any ideas it would be appreciated!

The error is:

Execution failed for task ':server:dependencyLicenses'.
> Missing LICENSE for slf4j-api-1.7.36.jar, expected in slf4j-api-LICENSE.txt

You can run ./gradlew updateShas to fix this
