[show] support for show muxcable firmware version of only active banks (sonic-net#1629)

Signed-off-by: vaibhav-dahiya vdahiya@microsoft.com

This PR adds support for an option to display firmware version of muxcable of only active banks.

The new output would look like this in case an active flag is passed to the command line

admin@STR43-0101-0101-01LT0:~$ show muxcable firmware version Ethernet0 --active
{
"version_self_active": "0.7MS",
"version_peer_active": "0.7MS",
"version_nic_active": "0.7MS",
}

What I did
added an option to display active banks only for display muxcable firmware version
