Added permission groups to user management page in console

[mscanlan-git]

This PR addresses #2105 by adding a permissions group section on the user's page in the console.

Currently, the template is set up to list "no group" if the user does not have any group affiliations, however, I'm open to suggestions on maybe hiding the section entirely if the user has no group affiliation.

Looks good, thanks Michael. I added a few very minor comments inline!

It feels slightly unnecessary to have a "No groups" bullet here. Could we instead say The user is a member of the following groups:... if there is one or more groups and something like The user does not belong to a permission group. if not?

We now have:

      <div class="col-md-9">
        <ul>
        {% for group in groups %}
            <li><a href="{% url 'user_group' group.name %}">{{ group.name }}</a></li>
        {% empty %}
            The user does not belong to a permission group.
        {% endfor %}
        </ul>
      </div>

For people who aren't in a group, this step will output The user does not belong to a permission group. inside <ul> tags which I think isn't quite right. I haven't tested, but what about something like this:

  <br />
  <h3>Permission groups</h3>
  <hr>
    <div class="row mb-1">
      {% if groups %}
        <div class="col-md-6">
          The user is a member of the following groups:
        </div>
        <div class="col-md-9">
          <ul>
          {% for group in groups %}
              <li><a href="{% url 'user_group' group.name %}">{{ group.name }}</a></li>
          {% endfor %}
          </ul>
        </div>
      {% else %}
          <div class="col-md-6">
            The user does not belong to a permission group.
          </div>
      {% endif %}
    </div>

I switched over to the new format, it made the else statement make more sense by not including the <ul> tag

thanks, looks good to me!
