Datum token rotation is not happening right now

[20vikash]

• With Datum as the metric/log service manager, central mints out 2 tokens - datum metric token, and datum log token
• The expiry of these 2 JWTs are 7 days.
• Line says that pilot will refetch the tokens when its near expiry.
• But currently there are no implementation of that in pilot side.
• We need a way for the token consumers to refetch/renew the tokens or make the tokens long lived.
