The addtions in this patch will add start/stop/restart/status
functionality to operations, so that Debian systems can perform
these operations by calling these functions from an init script.

We also introduce a parameter in the configuration scripts that
can be used to determine if the system is a debian system.  This
parameter is used to specify a system V init script instead of
a systemd script on a debian system, when the configuration
scriptlets start and stop a system.

Also source apparently does not work by default in debian.  Used
dot (.) instead.

tomcat now uses systemd unit files.  We will reuse and customize those
files accordingly.  As a result, startup is simplified considerably -
and pkidaemon has been gutted accordingly.

We'll need to add migration scripts for older instances in a subsequent patch.

Also added SuccessExitStatus directive to unit file to ignore exit value 143.
As a result of this setting, exit status 0 is returned.
