[rancid] Ciena Waveserver 1.6 - fluctuating power values + other improvement suggestions

[Chris Wopat]

We recently upgraded some Ciena Waveservers to v1.6, Ciena added power draw
info to the output of "show chassis". That value fluctuates a lot, causing
diffs on most rancid-runs. looking to see the best method to filter it out.

Attached is a .txt file (or see
https://falz.net/static/waveserver-1.6-chassis.txt)  with sample output
from 1.5 and 1.6m where the power column was added as well as a new box
displaying a total power value, which also fluctuates.

Is there a quick and easy way to filter out just the power values? If not,
a proposed solution would be to run these commands instead of 'chassis
show':

chassis show capabilities
chassis show mac

These would not show the power related info, but it would show the rest of
whats normally in the 'chassis show command'.

While looking in to this issue, we also notice that the command 'software
show' is run, but our diffs never show the output of it. If i run this via
command line, it does show output.

Lastly, there's a few other useful commands that I could see being added
fairly painlessly that show some useful information. Some of these came
from looking at what Juniper does already and some are unique to Fortigate
(the service things).

alarm show
blade show
license client show
license file list
service-domain show
service show map
