[show][muxcable] Decrease the timeout for show mux status/hwmode (sonic-net#2130)

Signed-off-by: vaibhav-dahiya [email protected]

What I did
Currently the response for hwmode muxdirection comes from ycabled. Since ycabled might not be running/exited state or
if the underlying hardware takes a long time to reciprocate the response for muxdirection, we decrease the timeout for the command, so atleast the user can see the output of CLI in 100ms.

How I did it
Added a constant timeout variable inside show/muxcable.py

How to verify it
Ran the change on Test DUT and unit-tests
