shill: Implement GetEntry on Profile

Implement "GetEntry" on profile_dbus_adaptor.  This change adds
the ability to look up a Service in the Manager by its
StorageIdentifier and then to return its properties to the caller.
If the Service does not exist in the manager, we have to read
directly out of the Profile's store and build a DBus property dict
out of its contents.  This is a pretty gross method, and I've already
created a bug to remove this as soon as we can diverge from the
flimflam Profile API.  crosbug.com/25813

BUG=chromium-os:25542
TEST=New unit tests + Manual: chrome://settings/internet now lists
both visible and unavailable networks under "Remembered Networks"
and clikcing on "Forget Network" purges the network from the profile.
