[c-nsp] 3750E cluster replacement

[Holemans Wim]

We do run lacp on most of our server, nas, .... connections. We also need these 2G channels towards our SAN to accommodate for the accumulated ISCI traffic coming from different servers. 3750E also have only one power supply, so we cluster them and use port-channels to protect against hw/power failures. Even when replacing the 3750E with nexus 55xx (if needed combined with FEX) we intend to double them and have portchannels on both.

You don't need the clustering if you run active-backup. It's only LACP that
requires a stack or virtual chassis.
