1. Providing a team name and api_key (Uses the slackr gem)
2. Providing a hash containing incoming webhook url(s)

Requirements

• The chef_handler cookbook
• An existing Slack incoming webhook(s)

Usage 1

1. Create a new Slack webhook (https://slack.com/services/new/incoming-webhook)
2. Set the team and api_key attributes above on the node/environment/etc.
