Subject: MM-10367: rewrite subpath assets on startup (#8944)

Examine ServiceSettings.SiteURL on startup and rewrite assets
accordingly if not in a development environment.

Also export `mattermost config subpath` command to manually do same.

This accompanies a webapp PR to use the updated `root.html` to define
the necessary webpack asset path for dynamically loading assets.
