[RAM] Slack api allowed channels (#167150)

## Summary

We add a lot of issue with our slack API by trying to fetch the
channels, so we decided to only use channel ID and create an allowed
list with channel IDs.

Here the new design:

# Connector Creation

# Slack Action Form
#### Creation of new slack api action in rule form
