Review Comment:
There is nothing wrong with adding new interfaces,
but I think deleting cookies is a bit risky and does not comply with data
integrity specifications. Although this is available in the old Command
command, I suggest you still go through the node offline process
`./bin/bookkeeper shell decommissionbookie [-bookieid <bookieaddress>]`
