Please add an example of using the --update options in the calls

In particular, I'd like to see an example of submitting an NSG update using JSON that adds multiple rules in one request.

Similarly, if it is possible to remove multiple rules in one request that would be useful to see as well.

Alternatively, a "replace entire NSG with this json" example would also be very helpful.
