URL: https://github.com/apache/tvm/pull/7951


   Encounter a special cases when batch_dims=1 in gather() from 
centernet_hourglass_512x512_1 from tensorflow hub model zoo. 
   Implement the batch_dims logic according to tensorflow implementation: 
https://www.tensorflow.org/api_docs/python/tf/gather
   
https://github.com/tensorflow/tensorflow/blob/5dcfc51118817f27fad5246812d83e5dccdc5f72/tensorflow/core/kernels/gather_op.cc
   
   I have not added testcases for topi and relay since numpy does not have that 
attribute, I am open to see any suggestion for that. Test cases for tensorflow 
frontend parser have been added.
