[xcvrd] initial support for integrating vendor specfic class objects for calling Y-Cable API's inside xcvrd (sonic-net#197)

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

Description
This PR integrates vendor specific class objects inside xcvrd for Y-Cable API's to be called.
Detailed designed document can be found sonic-net/SONiC#757

Motivation and Context
Basically xcvrd now has an interface for Y-Cable to interact with PMON docker and HOST
which can be uniform across all vendors. As part of this refactor, we will be moving towards a model where only xcvrd interacts with the cables/transceivers, and host-side processes will communicate with xcvrd rather than with the devices directly with Y-Cable.

How Has This Been Tested?
Ran the changes on Arista7050cx3 switch, making changes inside the container.
