ciju-juniper 3ff0c4d0dc [Juniper][QFX5210] Optoe driver for SFP management (#3438) 
* Adding platform support for Juniper QFX5210

This switch has 64 QSFP28 (40G/100G) ports, 2 SFP+ (1G/10G) ports
on Broadcom Tomahawk II chipset. CPU used in QFX5210-64C-S is
Intel Broadwell-DE. The machine has Redundant and hot-swappable
Power Supply (1+1) and also has Redundant and hot swappable fans (3+1).

* [Juniper][QFX5210] Optoe driver for SFP management

This commit implements the following changes
 - Moving to optoe driver for sfp management
 - Removing the old sfp driver
 - Updating the port-config.ini to add the index field
 - Correction in sfputil.py to incorporate optoe driver
 - Platform support for 'poweroff' command
