resources.py as CLI command

Hi,

The resources.py is a very usesul script and we need to add it in our bob bio CLI "umbrella" . Furthermore, we need to decide which type of resources should be kept and which should be dropped.

Today, the options available via -t are:

• d,database,
• p,preprocessor,
• e,extractor,
• a,algorithm,
• g,grid,
• c,config,
• an,annotator,
• b,baseline

I think now we should have something like:

• d,database,
• t,transformer,
• a,biometric_algorithm,
• d,dask_client,
• c,config,
• an,annotator,
• b,baseline
