This will be useful  in the situations where a particular host (or set of hosts) is causing some trouble for the broker.  Adminstrators can dynamically update these configs to restrict the connections coming from 

faulty hosts.

Proposed Changes

Use case: To restrict the connections coming from faulty clients/hosts

Config scope: Default for whole cluster (/configs/brokers/<default>)

Config options:

max.connections.per.ip
max.connections.per.ip.overrides

Dynamic update changes:

Above configs will be updated with the new values. Existing connections will not be affected, restrictions will be applied on
new connection creationsDescribe the new thing you want to do in appropriate detail. This may be fairly extensive and have large subsections of its own. Or it may be a few sentences. Use judgement based on the scope of the change.
