Add option to disable trapping signals

Description

Add an input option DebugTrapSignals to enable or disable trapping signals inside octopus. The default is to trap signals to handle the signals in octopus and print a custom trace. When setting to false, one can produce core dumps or use gdb to be at exactly the place where the signal was created.
