All three PRs are necessary to run show interfaces transceiver command.

1. Azure/sonic-buildimage#3912
2. Azure/sonic-platform-common#72
3. [sfputil] Add support of platform.json sonic-utilities#767

- What I did

Add support of platform.json in sfputilbase and sfputilhelper file. Code is duplicated in sfputilhelper file as sfputilbase is an abstract base class. So, it cant be instantiated.
