> {{AbstractDelegationTokenSecretManager#removeExpiredToken}} has two phases.  First phase
synchronizes to collect expired tokens.  Second phase loops over the collected tokens to log
them while not holding the monitor.
> HDFS-13112 needs to acquire the namesystem lock during the second logging phase, which
requires splitting the method apart to allow a method override.
