* AI: Added support for non BHWC models Tensorflow models use BHWC by default, however, if we are using converted models, we can find that the expected input is BCHW. Now the input is configurable (although the restriction of being dimesion 4 is still there) via Shape parameter on the input definition. Also, the model instrospection will try to deduce the input shape from the model signature. * AI: Added more tests for enum parsing ShapeComponent was missing from the tests * AI: Modified external tests to the new url The path has been moved from tensorflow/vision to tensorflow/models * AI: Moved the builder to the model to reuse it It should reduce the amount of allocations done * AI: fixed errors after merge Mainly incorrect paths and duplicated variables
