Add SLES support, correct autorestart doc

Puppet 2.6 is provided for SLES, it's init script sets a default puppet server, and the /etc/sysconfig/puppet file does as well.  I have added a config_init template for SLES, parameterized the application of init config file so as to select the proper template based on an OS switcher in params.pp.

Travis is failing, but the failures are the same as in your master.  I'm not well versed enough to fix the rspec stuff.
