Description

Our Marc Parisi indicates that using std::experimental is not prefered in production code, and causes compilation problems especially for compilers which do not have C++17 support.

Our usage of std::experimental::optional is very small and can be easily replaced with boost::optional. We depend on boost anyways for other reasons.
