[Juniper][QFX5210] Platform monitoring updates (#3899)

Browse Source 
As part of this commit, there are a few enhancements being
made for EM policy implementation: a) Introduced hysteresis
algorithm to prevent fan hunting b) Reading ASIC temperature
to make decision for fan speed.

As part of the PR# 3599, Workaround for the boot problem
from secondary bios was addressed. When the SONiC image is
upgraded, this resulted in creating multiple entries for
BOOTX64.EFI. To fix the problem, as part of this changeset,
introducing a check to see if there is already an UEFI entry
for BOOTX64.EFI and accordingly creating / skipping the UEFI
entry.
