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 Change-Id: Ic1314639dfc6a66c48ca87b6820707a2b0cb1dbd Partial-Bug: #1435306
