Description

This PR adds/fixes policy/policy version aliases.

It improves the way the primary key is computed/used. Update/Delete are required to use the primary key.

As a side effect:

• describe is removed from user/usergroup (it used an id when the primary key, used everywhere else, is the name)
• the usage help text now uses the primary key (in snake case), not entity_id

Additional fixes:

• delete cannot be called with no argument any more.
