Feature: support list-input to do_<x> measurement helpers

[mattijsjonker]

The do_<x> helpers to execute a measurement take a single "target" argument. E.g., do_dns takes a single qname and do_ping and do_trace take a single dst. It would be convenient (and beneficial) in some scenarios to be able to pass a list of "targets".

I agree. I want to make sure that this doesn't break event-driven use though -- currently event driven use requires one measurement in response to one "more". This feature could lead to the script up out of sync with what the VP is expecting to receive. I do plan to address this in the medium term.
