unsupported operators from tensorflow model garden models

[aaltonenzhang]

I'm checking tensorflow models from tensorflow models garden at https://github.com/tensorflow/models/tree/master/community.
For community models, there are types and operators which tvm doesn't supported. Most of them are quantize related, and some are not. I really hope these operators could be supported officially and I can check if these models work well.
The details are listed below.

model name	result
inceptionv3_int8	Op type not registered 'QuantizedConcatV2'
inceptionv4_int8	Op type not registered 'QuantizedConcatV2'
mobilenetv1_int8	The following operators are not implemented: {'QuantizeV2', 'Dequantize', 'QuantizedAvgPool', 'QuantizedDepthwiseConv2DWithBiasAndReluAndRequantize', 'QuantizedConv2DWithBiasAndReluAndRequantize', 'QuantizedConv2DWithBiasAndRequantize'}
resnet101_int8	The following operators are not implemented: {'Dequantize', 'QuantizedConv2DWithBiasAndRequantize', 'QuantizeV2', 'QuantizedConv2DWithBiasAndReluAndRequantize', 'QuantizedMaxPool', 'QuantizedConv2DWithBiasSignedSumAndReluAndRequantize', 'QuantizedConv2DWithBiasSumAndReluAndRequantize'}

Nit, it seems the embedded url (https://github.com/tensorflow/models/tree/master/community) in the above post is not the actual url shown, i.e. if you click the link you will go to different site. And I see the similar in #7198

@insop reedited the url links for both of the two issues.
