Enable colour in console output

[josecelano]

I've disabled color in the console output with .with_ansi(false).

let builder = tracing_subscriber::fmt().with_max_level(filter).with_ansi(false);

I've disabled it because we need to parse logs to detect running services and the color introduces hidden chars in the output.
