This patch is only moving all network observer files in the same folder.
For webdriver reviewers, we could update our phabricator herald rule to be added as reviewers for changes in this folder?

This is a very basic migration from commonjs modules to ESM for all modules related to network observation.
A few classes have been introduced instead of prototype-based classes, but otherwise the code remains mostly untouched.
We can followup to introduce private fields and methods if there's interest?
