Hardware and software discovery utilities

[botev]

It is needed that we have some form of utility which can list all of the available CPUs, GPUs and other compute hardware, including their model, and potentially specifications (e.g. number of cores, support of different extensions like e.g. does it support cuDNNv5, does it support AVX3 etc..)

On the software we side we need a utilities to check and find BLAS, LAPACK, cuBLAS, cuDNN, etc... libraries and being able to find their paths and versions for dynamic linking.
