Make source code directories read-only and write runtime artifacts to a writable location

[mssalvatore]

DRAFT

Monkey Island should avoid mixing runtime artifacts with the project's source code.

AppImage and Docker (to a lesser extent) already write runtime artifacts to a dedicated location, but some functionality is duplicated between them.

Windows could store the runtime artifacts in a location like %AppData%.

• monkey_island/cc/main.py configures datA

  • Monkey island defaults to writing runtime data to the "data_dir"
    • $HOME/.monkey_island on Linux
    • %AppData%/monkey_island on Windows
  • If no --server-config is provided, the default is "data_dir/server_config.json"
    • if "data_dir/server_config.json" does not exist:
      • create data_dir as readable only to the use (0700 on Linux)
      • copy default server_config.json to data_dir
  • if --server-config is provided and data_dir does not exist, create data_dir as readable only to the use (0700 on Linux)
  • If no --logger-config is provided, the default is "data_dir/island_logger_config.json"
    • if "data_dir/island_logger_config.json" does not exist, copy default island_logger_config.json to data_dir
  • [ ]

• Modify the Linux run script to use the new functionality as implemented in python.

• Modify the appimage/run_appimage.sh to use the functionality as implemented in python.

• Modify the docker build script to use the new functionality as implemented in python.

• Modify the windows run script to use the new functionality as implemented in python.

• Modify the MSI build script to use the new functionality as implemented in python.

• Update documentation to reflect where runtime artifacts are now stored.
