[sonic_y_cable]: Decorate all method for mux simulator (sonic-net#181)

Testbeds using the mux simulator will see lots of error messages in the syslog since many y_cable methods are not mocked for the mux simulator. This PR prepares `y_cable.py` to use mocked methods that will be introduced in a future sonic-mgmt PR.
