This change started out as a quick update to RHEL 7 support (aka systemd), in
the process I realized most of the other platforms could use an update. While
trying to cleanup there I discovered I was repeating of bunch of information
that might be better maintained in one place - as a result:
* consolidated server.sh and install.sh
* removed upstart-join.conf in a favor of join flag in the consul start
* removed platform specific folders and increased complexity of install.sh to
include handling the differences
* updated and extracted consul version
* added a consistent ip_table.sh file to open ports on firewalls
* updating consul service management configurations to enable proper restarting behavior for each platform
* the configuration naming convention is <distro_origin>_file_name
* added platform to the security group name so you can easily launch multpile platforms at once
* fixes#1304
