Match structured facts in mcollective

If you are using Facter 2+, which is what you do when you run at least Puppet4, then you have structured facts (meaning nested values) like those:

processors => {
  count => 2,
  isa => "unknown",
  models => [
    "QEMU Virtual CPU version 2.1.2",
    "QEMU Virtual CPU version 2.1.2"
  ],
  physicalcount => 2
}

Now you cannot match those using

mco find -F <fact name>=<fact value>

If you try you just get an empty result. The only way to match structured facts is using -S

mco find -S 'fact("<fact name>").value=<value>'

For example:

mco find -S 'fact("networking.network").value=192.168.5.0'
mco find -S 'fact("os.distro.codename").value=jessie'
