Simplify output of dirac-prod-get-all

The output of dirac-prod-get-all is a little bit long, e.g.:

399 Prod6_Paranal_div0.01135_rest_merge                                Active             627 2023-08-11 17:19:33 2023-08-11 17:20:53 /O=GRID-FR/C=FR/O=CNRS/OU=LUPM/CN=Luisa Arrabito cta_prod
400 Prod6_Paranal_div0.01453_proton_merge                              Active             628 2023-08-11 17:22:43 2023-08-11 17:23:44 /O=GRID-FR/C=FR/O=CNRS/OU=LUPM/CN=Luisa Arrabito cta_prod

Probably a shorter output would be more readable, e.g.:

Prod6_Paranal_div0.01135_rest_merge           Active             627 2023-08-11 17:19:33 
Prod6_Paranal_div0.01453_proton_merge          Active            628 2023-08-11 17:22:43
