Improve shim debug logging

- Add log statements in service entry points.
- Propagate `-debug` flag from shim invokation to the service
- Load options when shim process is invoked to ensure runsc commands
  use the correct set of options, e.g. --debug --debug-logs=...
- Add debug options to the shim configuration directly, so it doesn't
  rely on containerd configuration (and restart) to enable shim debug.
- Save shim logs to dedicated file, so it's easier to read logs. They
  would be mixed with containerd logs and hard to distinguish
  otherwise.
