This is removed as `os.scandir` throws exception if the directory doesn't exist, and it will also fail as it's not available in Python 3.4

**Features and improvements**
- 288 ReadMe update for building sandbox native command
- 296 JVM-based sandbox: expose all feature ports by default
- 297 Display date and time by default for Conduct Logs and Events
- 304 and 305 Improving help description
- 295 Move temp directory for JVM-based sandbox
- 306 sandbox restart command

**Fixes**
- 287 Conduct Deploy: modify digest to SHA-256
- 291 Fixing docker error handling
- 298 Separate cache dirs for bundle and configuration
- 299 Check bundle configuration cache dir permissions
- 303 Sandbox proxy - ensure proxy is started without any duplicated port declaration
- 300 and 307 Delete files under old cache directory
- 309 None check for ps keys

- 286 Use `sys.exit` instead of `exit` as native executable generated by PyInstaller doesn't recognize the `exit` keyword.
- 279 Implement `sandbox logs` command.
- 284 Handle docker validation during sandbox run.
- 283 Improved output of the `sandbox run` command
- 277 Modify `sandbox ps` to support cross-platform behaviour using `psutil` library.

The sandbox has been completely re-worked in order to avoid using Docker for containing ConductR itself. Network aliases are leveraged to start JVM processes and have them bind accordingly. This permits a cluster of ConductR cores and agents to reside on the OS without requiring Docker.

Note that the old sandbox approach is retained for 1.1, while the new sandbox applies to 2.0 only.

The `--wait-timeout` was interpreted as string and not as int. Therefore, an exception was thrown when speciying a wait timeout. Now it is interpreted as int.

Authentication settings is now scoped by host and port if configured, otherwise CLI will fall back to host settings.
