📜 Description

Add API for sending checkins (CRONS) manually.

Simplest usage looks like:

Sentry.captureCheckIn(new CheckIn("my_monitor", CheckInStatus.OK))

💡 Motivation and Context

One of the parts required for #2875

💚 How did you test it?

Manually, automated tests

📝 Checklist

Good Job 👍
Left some comments

[lbloder]

Constructor Params should be @NotNull annotated and final

[adinauer]

Will do in a follow up PR.

[lbloder]

Same as above @NotNull annotations and final for the params

[adinauer]

Will do in a follow up PR.

[lbloder]

Is that already decided? If so, we can remove the TODO

[adinauer]

Yes, shouldn't hurt to add it. Will do. Maybe in a follow up PR.
