Dave Wilde (d34dh0r53) 8f999d1c1f Limit token expiration to application credential expiration
If a token is issued with an application credential we need to check
the expiration of the application credential to ensure that the token
does not outlive the application credential. This ensures that if the
token expiration is greaten than that of the application credential it
is reset to the expiration of the application credential and a warning
is logged. Please see CVE-2022-2447 for more information.

Tokens issued with application credentials will now have their expiration
validated against that of the application credential. If the application
credential expires before the token the token's expiration will be set to
the same expiration as the application credential. Otherwise the token
will use the configured value.
