Add a retry mechanism for failed platform events

[jongpie]

Summer '22 adds a pilot feature that provides the ability to create callbacks for platform events, both for on success and on error. It'd be useful to leverage this to handle platform events that fail to publish (possibly due to exceeding the org's daily limit for platform events, etc)
