[Cluster-devel] [PATCH] Med: Improve script.sh's error reporting (RHEL6)

[Lon Hohberger]

The script agent used primarily by rgmanager had a very minimal amount
of error reporting, such that it could be very confusing as to why a
script resource had failed.

This patch looks for a variety of errors from the script resource.

Resolves: rhbz#773478
