feat(log): Show the current network upgrade in progress logs

[teor2345]

Motivation

It takes almost 6 hours for Zebra to sync all its checkpoints, so we need to be able to split CI jobs by network upgrade as well as checkpoint/full validation.

This is part of ticket #4661, it also includes a refactor I did as part of loading blocks from a file.

Solution

Features:

• Show the network upgrade in progress logs
• Log when Zebra verifies the final checkpoint

Fixes:

• Log elapsed time using humantime truncated to whole seconds, rather than raw seconds and microseconds
• Fix incorrect negative sign on elapsed time
• Remove the space before the percentage sign when showing percent progress

Refactors:

• Move the progress task into its own module

Review

This is a high priority because I need it for ticket #4661.

Reviewer Checklist

• Progress logs contain network upgrade
• Time is formatted nicely
• Existing tests pass

All looks great.

By reviewing this PR, I learned to compare only parts of different files against each other so that I can see what's changed, and what's just moved.

Yeah I find git diff --color-moved really helpful, I wish GitHub would do it automatically.
