Add support for Encrypted Syslog

While investigating the use of Syslog on our cloud hosted instance of ConnectWise, it doesn't appear that any type of Syslog encryption is supported. This exposes sensitive audit logging that would traverse the public internet to reach a syslog ingestion point. 

Rsylsog, Syslog-ng, etc support TLS encrypted communication which ConnectWise could connect to if supported.
