It is not necessary for all users to compile C++ code, which sometimes is a headache to do on highly custom built systems. Currently you can specify env variable `MOE_NO_BUILD_CPP`...

Grant user the ability to choose number of mc iterations for calculating ExpectedImprovement and gradient EI seperately

Motivation: While stochastic gradient descent algorithm has tolerance to the noise coming from monte carlo estimation of gradient, the noise from estimation of EI has great impact to the performance...

As GPU functions living in C++ interface are finalized, we need to create python callers that let users access GPU functions.

setup GPU PingTest

This ticket is to set up PingTest for GPU computation in `gpp_expected_improvement_gpu_test.hpp/cpp`. To do that, we need to ensure EI and grad_EI calculation use the same sequence of random numbers.
