Preparation for building with shared boost (#2611)

* Preparation for building with shared boost
Can be tested currently by ensuring `-DBOOST_ROOT=<path_to_boost_root> -DNANO_SHARED_BOOST=ON` are set for cmake
This will also require you have locally built static boost 1.67+
added switch for shared/static linkage to bootstrap_boost.sh default to static

* tabs vs spaces

* Verbiage for clarity

* '-j n' switch for bootstrap_boost.sh

allows for multiple jobs to be built at once with b2
