title: Hashicorp vault how to list all roles
body: <p>Is it possible to list all roles stored in a vault backend? I can't seem to find any reference on how to do so.</p>
  
  <p>From the documentation, it seems possible to list a role given the role name, through <code>auth/approle/role/my-role</code>, for example, but I don't see any references on how to list <em>all</em> roles stored in a vault server.</p>
