Title: Fix preflight display for thor under Target Cluster

After swap node, the preflight display for thor under Target
Cluster still shows the node which has beed swapped in as
spare node. That is because the existing preflight code
retrieves the node information from environment settings.
The new code reads the node information from Name Group
Store and, then, from environment settings.

We should check and display preflight information for
every slave nodes in one machine. We need to find out how
to identify the pid for each slave node.
