Scenario:
Sensor has a hostname of SENSOR1 (uppercase).
Setup currently forms a sensorname like SENSOR1-eth1.
If at some point the sensor has to be wiped and is reinstalled with the same hostname but lowercase (sensor1), then Sguil/Squert/MySQL will be inconsistent. Logging into the Sguil client will prompt for network to monitor and will show the OLD net-name (SENSOR1) which will then prevent any new alerts from being displayed. By forcing hostname to lowercase, we avoid case-sensitivity issues like this.
