Moved udev rules and systemd service to repository.

Refactoring code to support the multihost physical LEDs design.
https://gerrit.openbmc.org/c/openbmc/docs/+/55230

Moved the udev rules (70-leds.rules) and systemd service from
meta-phosphor to phosphor-led-sysfs repository. This daemon will
handle the udev events and service instead of copying from machine
layer.

Tested : Tested and verfied in Facebook YosemiteV2 platform.
