VIS as subdialog with UUI data

Restriction: This feature or information is available to Medallia employees only and it is not to be shared outside the company.

This customization for Charter is done on VIS 6.8 (VH 8.12) version.

When VIS is called as a subdialog application, Avaya UUI is passed as a subdialog parameter named "UserData" whose value is a JSON string as below,

UserData: {"Avaya_UUI":<"uui value">}

VIS will now check this UserData for UUI information which was not happening earlier. So now when VIS is called as a subdialog application it will first check the subdialog parameters (initial parameters in VIS) if UserData Json exist, and then reads the key "Avaya_UUI" as UUI, else it will consider the "avpAAI" (session.connection.aai) from platform variables as UUI.Code : https://github.com/VHT-StrategicServices/VXML-IVR/tree/6.8.CharterUpgrade
