Upgrade user management page (#2417)

Before, the use of the user management page was a little bit tedious
when there was many users. One must select a user to view some
metrics, to update it, or to delete it.
Now, the view is clearer because it shows all users at once with
their metrics. I introduced a detail page that repeats the metrics
but also allow to purge the user's feeds, to update or delete the
user.

This is the first step to make that page more useful and user-friendly.
I have in mind to add a pager for when there is a lot of users, a metric
to know when was the last time the user was using the application, and
a flag to know if the user has admin rights.

See #2096 and #2504 for ideas and inspiration
