jbosstools-composite-install_master sends lots of nag emails when something goes awry (as it should)

jbosstools-composite-install_master re-runs itself on failure. However, it seems like the SLEEP_TIME parameter is now ignored, resulting on constant re-run of the job and a lot of spam (multiple mails per minutes). Additionally to spam, this adds a relatively big load on Jenkins and slaves queue.
I've removed the re-run on failure block of the downstream job trigger as a temporary workaround.
