* libs/common: TrapSignal accepts logger as a first parameter and does not block anymore * previously it was dumping "captured ..." msg to os.Stdout * TrapSignal should not be responsible for blocking thread of execution Refs #3238 * exit with zero (0) code upon receiving SIGTERM/SIGINT Refs #3238 * fix formatting in docs/app-dev/abci-cli.md Co-Authored-By: melekes <anton.kalyaev@gmail.com> * fix formatting in docs/app-dev/abci-cli.md Co-Authored-By: melekes <anton.kalyaev@gmail.com>
