Exclude benchmark package from Core
Created by: J3FALL
Benchmarking module (see here) has significantly increased in size and already contains specific enums (BenchmarkModelTypesEnum, ...) , classes (ExecutionParams, CaseExecutor, ...), etc. More importantly, it adds several 'heavy-weight' dependencies, such as MLBox, AutoKeras, H2O, etc.
I think it would be useful to move benchmark module to a separate repository in the near future. It will allow to simplify the dependencies and the overall code-base of FEDOT.Core.
