Feature Request - External Validation should be able to test data in arrays

[joneubank]

Summary of request

Data from an array value and from value in an object nested in array should be able to be read and tested against an external service. In this scenario, we should be able to either pick the value from a specific postiion in an array, or test every value in the array against the external source

Additional detail: The current implementation only allows external validation of properties of the analysis that are Strings. If the JSON Path given in the external validation points to a value that is not a string, then the external validation will fail (and the logs will indicate no value read for that property).
