* State generator realtime uses strings Change the state generator's realtime data to return string values instead of number values. This exercises an edge case where enumerations could be a string instead of a number. Exposes #2018. * [Telemetry] handle string enumeration value Don't treat all strings as properly formatted enumeration values. Instead, check any input value against known enumerations and if one matches, return it. Otherwise, return input. Fixes #2018
