process: move initialization of node-report into pre_execution.js

- Splits signal handler setup code into two functions: one sets up `process.on('SIGNAL_NAME')`, another takes care of the signal triggers of node-report. Both should only happen on the main thread. The latter needs to happen after the node-report configurations are read into the process. - Move the initialization of node-report into pre_execution.js because it depends on CLI/environment settings.
