randomuniform Op in TVM

   Hi @MarisaKirisame 
   I understand now that in the new design proposed by you, we want to enforce 
unique random sequences every-time even if the input seed provided by user is 
same between multiple session executions. We are internally using C++11 
std::mt19937 generator for PRNG generation. There are no such API available in 
this generator which returns a new random seed value along with the output RNG 
object. Please see "src/runtime/contrib/random/mt_random_engine.cc" for more 
details.
   In such case how do you propose getting the new random seed. Also this piece 
of tvm code for PRNG generation(mt_random_engine.cc, random.cc) was 
pre-existing in contrib layer, we have just provided support in relay and topi 
layers so that it can be called by both these layers.
