Add tokio console for debug. (#317)

It requires `tokio_unstable` in rust flags, so a `tokio-console`
features is added to be compatible with the default config.
To compile with the tokio console enabled, compile with
``RUSTFLAGS="--cfg tokio_unstable" cargo build --release --features tokio-console``
The usage of the tokio console can be found in https://github.com/tokio-rs/console.
