@LesnyRumcajs @elmattic Please 🙏 can any one of give it a review.

This PR is not fully ready yet (naming, logging changes and need to remove extra command), just wanted to get some opinions on this, so I can proceed further.

Edit: To review only the snapshot progress tracker take a look at the last two commits

[LesnyRumcajs]

I'll let @hanabi1224 or @lemmih take a look; I don't have the capacity currently.

maybe it's OK to keep it for consistency

@akaladarshi Any ideas why some tests keep failing after a few retries? Please let us know if assistance is needed for investigating the failures.

The Snapshot test mostly fails because it is not able to download it before timeout.

I tried Devnet Check locally and it mostly failed because it was not able to download proofs and all.

I have seen these two test fail mostly in previous PR'S as well. Will try to dig deep.

@hanabi1224 While looking into this issue: I came across this weird behaviour.

While adding another RPC call SyncSnapshotProgress inside the Status subcommand which already has an RPC SyncState, the Devnet Checks starts failing.

That's the reason why the Devnet Checks was working in initial commits, because I added an extra subcommand Progress to check the snapshot progress.

Have you noticed this behaviour or can you give some pointers about it?
