Description

As of now, only collection specific handlers can be added to Solr. There is no way to add handlers that need to manage the cluster, instead of the collection/shard. Adding a hook that allows users to write custom handlers at admin/cluster level, which are initialized at core container level would be good.

The configuration for the same could be a part of either the properties file, or a separate file.

Addition/modification or the same could be done using the config APIs.
