Add automation hooks for setting/gettting preferences.

Add a test which excercises this, update old test.

Also,
  - Remove some old prefs hooks. They were not easy to use and required the user to know what a preference type was, with no way of listing them out.
  - replace if-else statements for json handlers with a map.
  - Fix json error strings. json prefers " over ' (automation_provider.cc)

BUG=42701
