Add support for session tracking

[johnfoconnor]

Summary

Add support for session tracking into the SDK, for measuring release health
https://docs.sentry.io/product/releases/health/setup/

Motivation

Sentry is MUCH more useful when you can understand release health and associated session metrics. Many other Sentry SDKs support this, golang should as well.

[rhcarvalho]

While we are eventually going to roll Release Health into more platforms, currently we support just a few as we iterate and validate the product.

We can use this issue to track interest and help us prioritize.

Related to #335.

Is there any update on this? We've hit this issue and were super surprised that the Go SDK was missing this feature. It's pretty key for us understanding how migration is going for the tools we're developing.

This forces us to use Datadog to track this, when Sentry is really where we want to visualize it 😭

Hey @mikepea, thanks for reaching out!

I know it sucks. We are looking to adopt session tracking in this SDK too. I am hopeful that we can pull it in around January.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!

Has your 2021 iteration and validation completed? Any plans to roll this out to golang?

I'm reopening this, though I can't commit to any timeline for when this feature will ship in the Go SDK.
