shill: add MockIcmpSession, IcmpSessionFactory, and MockIcmpSessionFactory
Add MockIcmpSession class that allows for mocking of
IcmpSession function calls. Add an IcmpSessionFactory and
a corresponding Mock of this factory to allow IcmpSessions
that are dynamically allocated within a class implementation
to be mocked in unit tests.
A forthcoming CL will use these classes for testing.
BUG=None
TEST=Compiling shill for unit tests succeeds.
