Review Comment:
Understand. How about define a new CurrentUserDelegationTokenProvider mainly
for refresh the tokens added into container launch context? They are useful as
these tokens are returned for setup execution context for containers. When a TM
failure or JM recover from HA mode, these tokens need to be still valid.
