chore(l1): improve logging on the import subcommand.

[mpaulucci]

Motivation
Logging in general, and specifically in the import subcommand is quite messy.

Description

• Improves the logging phrasing
• Instead of logging for each block, logs a summary every 10 seconds
• Logs the total time that it took.
• Some misc log additions and downgrades

This is how it looks:

unrelated to the PR but it is such a small fix that I added it
