Remove D-Bus dependency from Config

This is achieved by using a generic ConfigAdaptorInterface to communicate
with the adaptor.

Use FakeConfigAdaptor for testing, which provides the storage for
the property variables.

While there, update the Config APIs to use the generic internal Error type
instead of brillo::Error (which is tailored more towards D-Bus). The D-Bus
adaptor will convert it to brillo::Error when returning from D-Bus method
calls.
