SiteSync: host dirmap is not working properly (#4563)

- only editable keys are returned from Site Sync module to Local Settings

Cleaner approach even if LS UI is going away in Ayon.

- use remote_site only if is local_drive provider

- remove unwanted import

- cache mapping, update logging

Mapping was called multiple times for Nuke.
Logging was too verbose.
