HBASE-23208 Unit formatting in Master & RS UI

[karthikhw]

ProcV2 use org.apache.hadoop.hbase.procedure2.util.StringUtils#humanTimeDiff(long) and humanSize(double) where it returns human readable string. I think it would good if we format the string before we return it.

The same format will apply to master and regionserver logs. I hope no one will concern about this format change.
