#78 EoN: Uses non-unique ClientID

Milestone: 1.0.0.0: EoN

Every EoN Node must have the same GroupID.
Every MQTT Client must have a unique ID.
IS: Client ID = GroupID (non-unique)
SHOULD: Suggest: ClientID = GroupID + EoNID . Then Strip illegal characters and shorten to 23 characters (take the right)

Background
From MQTT Spec: "The Server MUST allow ClientIds which are between 1 and 23 UTF-8 encoded bytes in length, and that contain only the characters "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ" [MQTT-3.1.3-5]."
