Add optical power info on amps in/out ports

[EstherLerouzic]

This was raised on issue #45, as a use case for ports info. But finally we agreed to not have ports, but we did not follow up on the need for optical power (did not find an issue on that, so I start this one).

Optical power is especially needed to recompute / check consistency of span (fiber+concentrated loss) loss value, with respect to loss/gain information on elements.

see the tree proposal at #46 (comment)

in the proposal there is output-power new attribute , and the description in YANG could be: " it represent total output power measured in the range specified by fmin and fmax .

Hi @EstherLerouzic, are you proposing a mandatory or optional parameter?

[EstherLerouzic]

Yes I would prefer it mandatory

Hi @EstherLerouzic, are you proposing a mandatory or optional parameter?

We discussed that during the meeting on 14 December and we say that the attribute should be mandatory.
Italo proposed to call the attribute "total-output-power".

We need:

• to add attribute "total-output-power" in the container "operational" in the grouping "amplifier-params"
• description : "It represent total output power measured in the range specified by fmin and fmax . Optical power is especially needed to re-compute / check consistency of span (fiber+ concentrated loss) loss value, with respect to loss/gain information on elements."
