Allow to specify udp port in syslog_host

[JrCs]

Hi, i want to use chaperone to relay syslog messages to logstash (that not running as root, so can't bind to port < 1024). So can you allow to specify the port where the syslog messages are sent in the syslog_hostoption. Ex:

syslog_host: "logstash:1514"

Thanks
