Pino Toscano 2fb2422da8 Make almost all the element scripts as e/u/pipefail
Following the latest dib-lint reporting, make sure almost all the
scripts are enabling -e, -u, and pipefail.  This eases the discovery of
failing commands, and the usage of unset variables.

There are few exceptions with flags not set:

* elements/hadoop-hdp/install.d/40-install-hdp, set -e
  when installing HDP 2.0, it tries to install tez, which does not seem
  to exist in Hortonworks' repositories

* elements/ssh/install.d/33-ssh, set -e
  the version of augtool (part of augeas 0.10) in older Ubuntu versions
  (like Precise, needed by the cloudera plugin) exits with wrong return
  values in autosave mode

* elements/storm/install.d/60-storm, set -e
  It tries to change the permission of /etc/supervisord.conf, which does
  not seem to exist
