deltacloud-core should pass back better error messages from RHEV-M errors
-------------------------------------------------------------------------

                 Key: DTACLOUD-88
                 URL: https://issues.apache.org/jira/browse/DTACLOUD-88
             Project: DeltaCloud
          Issue Type: Bug
          Components: Server
         Environment: Fedora-15, deltacloud-core-0.5.0-0.2.1317167702git.fc15.noarch (nightly)
            Reporter: Chris Lalancette
            Assignee: David Lutterkort


When trying to run a RHEV-M action (lib/deltacloud/drivers/rhevm/rhevm_client.rb:vm_action()),
the action may fail.  If it does, deltacloud-core returns a pretty generic: Operation start
failed.

However, we can do better.  If an action fails, RHEV-M returns a piece of XML with detail,
like:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<action>
    <status>
        <state>failed</state>
    </status>
    <fault>
        <reason>Nogah operation failed</reason>
        <detail>[Cannot run VM. VM is not found.]</detail>
    </fault>
</action>

We should parse that detail out and return it as part of the exception so that the client
will have a better idea of what the problem is.
