TrainProject returns BadRequest when there are not enough images or tags

[malantin]

The TrainProject method fails with the exception message "BadRequest" when there are not enough images (<5) or tags (<2). The exception should provide a meaningful message like the one you get on the portal.

In particular, the message code returned from the server should be propagated back up to the caller, e.g., given the response

{"Code":"BadRequestTrainingValidationFailed","Message":"Not enough images per tag for training"}

it would be helpful if the Message value became the associated message detail for the exception.
