rework service and fix service for debian jessie

- use ::vswitch::params for service parameters
- on debian jessie openvswitch has now proper init scripts
  with status. This patch avoids restarting ovs on each
  puppet run on jessie.
- this patch breaks debian versions older than wheezy
  (which are not supported by debian anymore)
