Allow to pass single parameters at `tw launch` command

[jordeu]

Description

Current launch version only allow to pass parameters using a file, with the option --params. To mimic as much as possible the nextflow run ... command here we propose to add the option to pass pipeline parameters from the command line.

Example usage

tw launch pditommaso/nf-sleep -P timeout=20 or tw launch pditommaso/nf-sleep --param timeout=20

Implementation details.

• See picocli map options here.
• We propose to use -P uppercase, to avoid confusion with the nextflow run ... -p that refers to profile.
• If the user provides a params file and also command line parameters, the command line parameters should override the file parameters.

I would really like this as well! Especially for input and outdir parameters which change for every launch.
