Support for Crons on Hangfire

[bruno-garcia]

Problem Statement

Crons is in Beta: https://docs.sentry.io/product/crons/

Other SDKs:

• Celery beat PR: Add support for Sentry Crons to Celery Beat sentry-python#1935
• Laravel: feat: Add support for Scheduled Tasks monitoring sentry-laravel#659

Solution Brainstorm

Spec is pending, this can be on hold until then.

@kanadaj already created something for Hangfire (and Quartz) that can be brought in or used as inspiration: https://github.com/kanadaj/Sentry.Monitor

Hangfire is mostly about fire-and-forget background tasks. We'd be mostly interested their recurrent tasks feature.
https://docs.hangfire.io/en/latest/background-methods/performing-recurrent-tasks.html

We should also look at Quartz.NET, which is primarily aimed at scheduling.

Also, there are several cloud-based schedulers offered by Azure, AWS & GCP - but I think those should be broader initiatives, not specific for .NET.

Note, this issue mirrors getsentry/sentry#44377

Also, this has already been started externally, by @kanadaj at https://github.com/kanadaj/Sentry.Monitor

I use it as a recurring job runner on: https://github.com/dotnet/nuget-trends and plan to dogfood there

Deleted Quartz from the title. Lets scope this to Hangfire only. if there's demand for Quartz we can create another issue and track separately.

@bruno-garcia My implementation already has both Quartz and Hangfire and seems to work fine unless the API changes for some reason.

Edited the title to note that your code has both and we can talk about moving it in to this repo 🙏 Thanks!

This was discussed on Discord, but for recordkeeping: if we want to make these more generic libraries (Sentry.Hangfire and Sentry.Quartz) we'd probably want to also add facilities for tracing the jobs. This could be done for non-recurring jobs too.

For reference, I'd love to have an implementation for Quartz.
