[j-nsp] GRES on EX-Virtual chassis

I always configure my VC-EX switches all with priority 255.
If they have different priorities you can't manually failover and as mentioned other weird stuff happens.

IIRC, when you have a two switch EX4200 VC, it's mandatory to set the priority manually to 255 on both members, otherwise weird stuff might happen. I run a pair like this and it's been stable for more than a year now.
