Unable to wait for more than ~20 seconds on application start with --debug-brk

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 5.2.0 (the current next)
• Cross-platform modules: 5.1.0
• iOS Runtime: 5.1.1

To Reproduce

1. tns create myApp --js
2. tns debug ios --debug-brk (on a real iOS device)
3. open the debug URL in chrome
4. wait on the first line for more than 30 seconds (the app will be killed and the debugger disconnected)

Expected behavior
You should be able to wait there as much as you want

Additional context
The app is killed by iOS. We've solved this issue for simulators by attaching an lldb debugger to the application (check out the iOS simulators application manager). We should implement a similar solution in the ios-device-lib - we could use some gdb options in order to attach a native debugger to the app when waitForDebugger is passed.

從 tns debug ios --debug-brk 進入點開始，檢查 ios-device-lib 對 waitForDebugger 的處理方式，並與 iOS 模擬器應用程式管理員的行為進行比較。在實際的 iOS 裝置上重現，並驗證附加原生偵錯工具後，應用程式與 Chrome 偵錯工具的連線能維持超過 30 秒。
