This reorganizes the content of web_monitoring into a hierarchy of modules with several directories based on this discussion: #206 (comment)

        cli.py               # Entrypoint -- parses args and calls other modules
        ia_healthcheck.py    # Currently in scripts folder

• diff
• diff_server (I renamed the module itself to diff_server/server.py)
• cli
  • Main cli.py file
  • ia_healthcheck script
  • annotations_import script

As part of moving the scripts, I’d like to reconfigure our CLI setup so we only have two scripts: wm and wm-diff-server. The wm command currently has wm import ia and wm import ia-known-pages subcommands, and I’m thinking I’d add wm ia-healthcheck and wm annotations-import. I think there might be room to rethink the command names and structure more, but that’s probably out of scope for this PR (making this script change is already questionably big).

Out of scope, but probably things we might want to do after this PR:

• Split up the contents of diff_server/server.py.
• More relative imports everywhere.
• Reorganize/rename some of the stuff in diff.
• Break apart the insanity in cli/cli.py a bit.
• Consider whether any of these new directories should have __init__.py files for easier access to subpackage contents.
