More fixes for the automated installer (now redis and mongodb are set to
auto-restart after a reboot when installed in RHEL distributions)

Fixed a bug where the configure utility would always fail, unless the
dependencies were installed through the automated installer.

Added dependencies files for automatic installation of the following
Virtual Application types: nullworkload, filebench, coremark, netperf, ddgen

Updates on the OpenStack cloud adapter to print more verbose error messages
whenever the Controller Hostname/IP is not resolvable by /etc/hosts or DNS.

Updates to have the automated installer working on AMI linux distribution
