Handling for Channel events

[iancward]

Description

Hello, I'd like to have Hubot be able to send notifications to a channel when a channel is created, archived, or deleted. I've found some code examples using robot.adapter.client?.on? 'raw_message' but when I used it, I received a deprecation warning:

WARNING SlackClient#on() is a deprecated method and will be removed in the next major version of hubot-slack. It is recommended not to use event handlers on the Slack clients directly. Please file an issue for any specific event type you need.
Issue tracker: <https://github.com/slackapi/hubot-slack/issues>
Event type: raw_message

It looks like there are some event handling capabilities already; however, I'd like to use these, which don't appear to be included:

channel_archive
channel_created
channel_deleted
channel_rename
channel_unarchive
