Remove revoked tokens from the Cluster Agent Tokens API endpoints (REST and GraphQL)

This came up from these discussions:

• !103170 (comment 1166261095)
• Sync standup discussion (7 November 2022), item 3 raised by Pam

Summary

Currently, the Cluster Agents API -> Agent Tokens endpoints return the revoked tokens on GET requests.

We (~"group::configure") came to the agreement that for the next major milestone (16), revoked tokens should not be shown/included in the APIs (REST and GraphQL) and the UI.

The UI already does not show the revoked tokens, but the APIs should be updated.

• REST API
  • List tokens - documentation | code
  • Get a single token - documentation | code
• GraphQL
  • ClusterAgent.tokens - documentation | code
