[c-nsp] Port-channel not working Juniper vs Cisco

[Saku Ytti]

You've changed JNPR from 30s to 1s, but not CSCO. I'm not sure if this
is the only problem, as insufficient data is shown about the state and
LACP PDUs.

I believe the command is 'lacp rate fast' or 'lacp period short', to
reduce risk of operators getting bored, In your case, the former.
