Then the error would be duplicated on the console. We already print the 
whole task log,
which includes the error. Including the error in `bail` would produce an 
output simillar to this:
```
root at debian:~# PBS_LOG=info proxmox-backup-manager pull 18.201 test1 test1
pull datastore 'test1' from '18.201/test1'
TASK ERROR: Querying namespaces failed - HTTP error 400 Bad Request - no 
such datastore 'test1'
