Insufficient input validation on set_whitelist_blacklist, add_greylist_accounts, remove_greylist_accounts

There is nothing "ok" about this request:

curl -d '{"foo":["bar"]}' http://127.0.0.1:8888/v1/producer/set_whitelist_blacklist
{"result":"ok"}

Input validation is required to ensure what is being submitted actually changes configuration.

Short-term solution to address this issue requires that at least one of the optionals must be provided.

That would definitely have saved some time.
