(FM-2790) Return SQL installations as Facter facts

 - Fact 'sqlserver_installs' contains all detailed installation information
 - Fact 'sqlserver_instance_names' contains all instance names
   segregated by SQL version
 - run_discovery_script method has been completely removed in favor
   of leveraging Facts

 - note that to make the output compatible with Facter, the Ruby symbols
   used in the hashes returned from PuppetX::Sqlserver::Features have
   all been changed to bare strings
