Unable to list products as user

[dsavineau]

As a user, I can't list the product even if I'm subscribed to topics associated to that product.

$ dcictl topic-list
+--------------------------------------+------------+--------+-------------------+----------------+-------+--------------------------------------+--------------------------------------+
|                  id                  |    name    | state  |  component_types  | export_control | label |            next_topic_id             |              product_id              |

Compared to the admin user:

$ dcictl product-list
+--------------------------------------+-------------+--------+-------------+-------------+--------------------------------------+
|                  id                  |     name    | state  | description |    label    |               team_id                |
