Bump used Go version to 1.17
What does this MR do?
Updates the used Go version to 1.17.x
This is a successor of !2763 (closed).
Why was this MR needed?
We're currently on 1.13.8, while the recent stable version of Go is 1.17.x. We're - AGAIN - on an unsupported version of Go.
Since we're not blocked (or rather - we don't know about any blocker) from bumping the version up, as we were with Go 1.8, let's just do this. And see if all is OK
What's the best way to test this MR?
What are the relevant issue numbers?
Closes #28159 (closed)
