Bug 1131139

oo-mco is installed on nodes due to rpm configuration, however the scl mco executable is not. Added error message to avoid confusion for newer administrators.
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.

Bug 1108762 - Need to install v8314 package to start openshift-broker service
https://bugzilla.redhat.com/show_bug.cgi?id=1108762

openshift-broker requires v8 at startup, but the packaging did not
express this requirement. Modified so it does.
