[show][config] add support for setting and displaying switching modes…

… on Y cable (sonic-net#1501)

Summary
There is also support for new commands for muxcable/Y cable
show muxcable hwmode switchmode
sudo config muxcable hwmode setswitchmode manual/auto all
which can basically set/display the switching modes on the cable to auto or manual
using the cli

What I did
Also added these new commands

admin@STR43-0101-0101-01LT0:~$ show muxcable hwmode switchmode 
Port       Switching
---------  -----------
Ethernet0  manual
Ethernet4  manual
admin@STR43-0101-0101-01LT0:/usr$ sudo config muxcable hwmode setswitchmode manual all
Muxcable at port all will be changed to manual switching mode. Continue? [y/N]: y
Success in switching mode on port Ethernet0 to manual
Success in switching mode on port Ethernet4 to manual
admin@STR43-0101-0101-01LT0:/usr$ sudo config muxcable hwmode setswitchmode auto all
Muxcable at port all will be changed to auto switching mode. Continue? [y/N]: y
Success in switching mode on port Ethernet0 to auto
Success in switching mode on port Ethernet4 to auto
