shill: Implement write-only properties
Certain properties (e.g. WIFI Passphrase) are write only and must
not be returned when Service.GetProperties() is called over D-Bus.
This CL implements WriteOnlyProperties, a write-only analog of the
read-only ConstProperties.
Also add a ReadablePropertyConstIterator which only returns the
readable properties. Switch over DBus adaptor and PropertyStore
to use that.
