THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
When running kafka-metadata-quorum script to get the quorum replication status, the LastFetchTimestamp and LastCaughtUpTimestamp output is not human-readable.
I will It would be convenient to add an optional flag (-hr, --human-readable) to enable a human-readable format showing the operation delay in ms (i.e. 366 ms ago).
This dealy delay is computed as (now - timestamp), where they are both represented as Unix time (UTC based).
...
A new optional flag called --human-readable with the shortcut -hr will be added to the kafka-metadata-quorum tool.

Proposed Changes
The current default --replication output is as follows and will remain unchanged.
...
Instead, when passing the new flag, we will have the following output (note how argparse4j support abbreviations).
