add interactive mode to see output

[colorcube]

No idea if this is easy to implement or breaks the concept.

Tasks could be configured with '--quiet'. Executing crontab from the command line gives you no feedback.

For testing purposes it might be good to have an --interactive switch which shows the tasks output (disable --quit)

Maybe additionally to arguments: there could be an option argumentsInteractive: which will be used for interactive mode if set

Example

        process:
            type: command
            command: cleanup:updatereferenceindex
            arguments:
                - '--quiet'
                - '--no-interaction'
            argumentsInteractive:
                - '--no-interaction'
