This wrapper runs a qemu command, record command output and plugin
output, and forward both to a check script.
We use this pattern in several plugin tests (for instance, with
validate-memory-counts.py).

Could we write a single python script for all the shell script wrappers
and use a different kind of wrapper depending on its command line
flags/subcommand we invoke it with?
Maybe this could be better? WDYT?
