Handle PagerDuty API rate limiting

[mjiderhamn]

PagerDuty API has rate limits; see here and here. I would like to see this handler tackle the issue of hitting the rate limit (for example in case of a larger outage).

Maybe something like number of --retries parameter? Maybe even with configurable backoff, multiplier etc?

This is a good idea.
We are seeing PD API call misses from time to time, and no clear way to make it retry.

Hey folks, one other user brought the project https://github.com/martindstone/PDaltagent to our attention, which handles queuing of PD events. Have you taken a look at that to see if it would do what you need? With the new ability to specify an alternate endpoint (e.g., pointing the pd handler at the agent from that project), this would enable you to get around rate limiting, I believe.
