[Juniper] Re-organizing sonic_platform modules (#4448)

This patch set implements the following:
 - Fixes the conflicts in chassis.py / platform.py in sonic_platfrom
 - Consolidating the common library files in sonic_platform
 - Moving QFX5210 specific drivers to qfx5210/modules
 - Moving Juniper common fpga drivers to common/modules
 - Cleaning up the platform driver files
 - Bug fixes in QFX5210 platform monitor & initialiazation script
 - Fixing the bugs in QFX5210 eeprom parsing
