Improve Slack Notification Error Handling

ISSUE TYPE

• Enhancement

COMPONENT NAME

• API
• UI

SUMMARY

Currently we only surface errors when sending slack notification if a Python exception occurs. We could do better if we read the event stream after our rtm_send_message call to see if there were any error events waiting.

A common error is when the bot has not been invited to a channel that we are attempting to send the notification to. This can be caught in the message stream, but does not throw an exception.
