<p>This hook allows you to post messages to Slack using incoming webhooks.
Takes both Slack webhook token directly and connection that has Slack webhook token.
If both supplied, http_conn_id will be used as base_url,
and webhook_token will be taken as endpoint, the relative path of the url.</p>
<p>Each Slack webhook token can be pre-configured to use a specific channel, username and
icon. You can override these defaults in this hook.</p>
