Initial systemd service files

If you want to use this, please copy and rename puppetdb.systemd.params
to "/etc/conf.d/puppetdb". puppetdb.service expects this file there.
updated rakefile and tasks for suse support

Updated Rakefile to create suse specific files
Updated template to create suse init file

Conflicts:

	Rakefile
fixed suse init file, copyright line merged
add missing sysconfig defaults
otherwise init script won't work
updated spec file suse support

This change wil make puppetdb rpm building possible on opensuse
with the same spec file as redhat.
Only requirement missing is lein / clojure on suse
So build it locally with lein from download script.
improved systemd.service file with template erb
The template task will provide the right systemd file.
Removed the params as it is not needed with template

Small fix on suse init file template, removed puppetdb name
in favor of templated variable namespace.

Conflicts:

	tasks/template.rake
