add git commit hash and compiler info to logging and version calls (#2170)

* add build info to version calls

* use Boost defines to gather Compiler info as well as bash version
New build_info example ```Version 20.0
Build Info 3d66a9a9 "Clang version " "10.0.1 (clang-1001.0.46.4)" "BOOST 107000" BUILT "Jul 23 2019"```

* prevent multiple flushes
