Subject: [PATCH] location,schema: Keep max accuracy in gsetting

Instead of relying on geoclue to store this user configuration, lets
keep it in gsettings. Geoclue is a system service and therefore is not
the appropriate entity to keep this info.

+        what Geoclue will allow applications to see and they can find user's
