NodeLogger: add attrs to log, parse execute_parallel actions

Bug 1139359 - node platform logs do not provide context attributes consistently
https://bugzilla.redhat.com/show_bug.cgi?id=1139359

This fixes platform context logging such that it works for
execute_parallel agent requests.

Additionally, the available context attributes are expanded to include
app_name, app_namespace, and (where applicable) cart_name.
