Provide example of setting up network teaming/bonding

[phillxnet]

Splitting out the teaming update from: "update network section" #130 to help with focusing these required network update tasks as we now have quite a few updates required in this section.

Please see issue #130 for context:

"And we also have teaming and bonding capability now. Perhaps, given at least 802.3ad also requires switch configuration, a concrete example covering the switch config would be good as a separate howto.
Linking to a recent forum post on bonding/teaming where I have produced some required images for this howto:"
