Utils-core

* Allow exception class to be changed for timeout and use SystemExit for processify

SystemExit will ensure everything are terminated, while other exceptions may be caught and not handled
properly (even another BaseException)

* Add timeout function and support to processify

* Add processify to run function in a subprocess

--------------------------------------------------------------------------------

* Add run_sync to run sync func in async program

--------------------------------------------------------------------------------
