[PATCH v2 06/32] test: Use new-style contexts for passt pane in the pasta and passt tests

[David Gibson <david@gibson.dropbear.id.au>]

[-- Attachment #1: Type: text/plain, Size: 4308 bytes --]

Convert the pasta and passt tests to use new-style context execution
for the things that run in the "passt" frame.  Don't touch the
passt_in_ns or two_guests tests yet, because they run passt inside a
namespace which introduces some additional complications we have yet
to handle.
