Adds a new function to SparkSessionExtensions def injectFunction(functionDescription: FunctionDescription) Where function description is a new type type FunctionDescription = (FunctionIdentifier, FunctionBuilder) The functions are loaded in BaseSessionBuilder when the function registry does not have a parent function registry to get loaded from. ## How was this patch tested?
