Syslog name translation (#9463)

Browse Source 
* Check to see if a host exists in a lookup table to translate received name to what LibreNMS knows

* Added some documentation on how this is configured

* Use \LibreNMS\Config instead of accessing $config directly

* Fix codeclimate finding: Additional blank lines after USE statement

* murrant suggested a much cleaner way of doing this!
