Rename OSC devices and refactor LED setup
- on ROADM Line Degree modules, use "osc" for "eth2",
- on inline amplifiers, use "oscW" for eth2 and "oscE" for the PCIe
add-on NICs,
- otherwise, keep the name as-is (eth2)
And because I'm touching the service which sets up the LEDs, let's
convert it into a shellscript, these one-liners are starting getting
rather scary. This means that:
- I'm splitting these per-function, so SFP netlink activity is separate
from EDFA indication setup,
- correct LEDs are now used for the inline amplifier
