fix: improve consistency of log fields

What does this MR do?

• Log the domain query parameter with a consistent name and differentiate between domain_query and domain_host.
• Avoid duplicate logging of fields handled by LogRequest (host, path, correlation id)
• url -> archive_url in the vfs package (this is consistent with the archive_key field)
• use lookup_name consistently in the gitlab client code

Closes Consistent use of `domain`, `pages_domain` and ... (#785 - closed)
