network: Rename _sync_psk to _sync_settings

There will be additional security-related settings that will be
introduced for settings files.  In particular, Hash-to-Curve PT
elements, Transition Disable settings and potentially others in the
future.  Since PSK is now not the only element that would require
update, rename this function to better reflect this.
