[shill] Add support for setting properties.

This CL adds a framework for supporting RPC-exposed properties in Shill.
It also plumbs the code for setting properties on Service objects to prove
the approach.  Device and Manager settings will follow.

BUG=chromium-os:16343
TEST=build shill, run unit tests.
