Add Facility Option for Syslog destination

Detailed Description

Add an option to choose which facility will be used when sending to the destination.

Use Case

Currently sending logs to Solarwinds SEM, and the log is going to the /var/log/user.log, and since I cannot change the "facility", I can not force it to go to an unused log file.

Workarounds

None
