Implement Retry-After during heartbeats import

[muety]

Proper rate limiting middlewares (including caddy-ratelimit) will return a Retry-After header alongside 429 requests.

The WakaTime heartbeats import mechanism should respect this and retry the request instead of failing.

Is this supposed to be implemented in the WakatimeRelayMiddleware where it sends the heartbeat to wakatime api? Or is there a separate importing mechanism that I am missing out?

Also, we should stop retrying after a certain number of times. What would be the best number for retrying attempts? Should there be a config for that?

Hi @Zubayer204, thanks for jumping onto this. The retrial would be implemented as part of the WakaTime import mechanism - not to be confused with the relating, which is "opposite" direction.

But now that I think about it, to be honest, I think I'd want to implement this myself. Nit because I wouldn't trust your skills or something, but because I'd find it interesting to dive deeper into that topic.

Generally, you did everything just right by looking for the help wanted label.

Hope you didn't put too much work into this yet! Sorry.

No worries! I appreciate your work. Thanks for making such an amazing project happen!
