Revoke an Agent Token from the UI

What does this MR do and why?

The MR adds a possibility to revoke agent tokens from the UI using the Revoke token button from the Tokens tab on the Agent page.

Definition of done

• The revoke button is present in the agent access token list.
• The revoke button is disabled for users with less than maintainer role.
• For users with at least maintainer rights clicking on the button opens a confirmation popup.
• The popup contains an input to confirm the revoke action and a cancel button.
• After the token was revoked, the token list gets updated.
