Adding Operator Inputs into SiteWise

In an Industrial environment, the Operators can be an important source of information, for instance, they can enter the machine status (In maintenance, Stopped, Waiting parts from the productions line, operator in break,...) and it can be used to calculate metrics such as OEE (Overall equipment effectiveness).

Architecuture

** The Code in this repository covers only the Operator input path (HMI to SiteWise)
