Reduce verbosity during context execution

Hi,

Just set the verbose level to ERROR or even INTERNAL_ERROR.

https://docs.nvidia.com/deeplearning/tensorrt/api/python_api/infer/Core/Logger.html?highlight=info#tensorrt.ILogger.Severity

For example:

TRT_LOGGER = trt.Logger(trt.Logger.ERROR)
runtime = trt.Runtime(TRT_LOGGER)

Thanks.
