Migrate to Alpine 3.10

The image is pretty big in my opinion, its possible I guess to move it to Alpine 3.10.

Oh please do this I really want to just have the app and Traefik in front of it! Far nicer for adding too many web apps into my self-hosting rig.

The migration to Alpine 10 should be possible.
The problem could be in not using NGINX, as Taiga requires to set routing externally for different components such as events queue, frontend and backend on the same domain.

Example:

{% if TAIGA_ENABLE_EVENTS.lower() == 'true' %}
        location /events {
            proxy_pass http://{{ TAIGA_EVENTS_HOST }}/events;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_connect_timeout 7d;
            proxy_send_timeout 7d;
            proxy_read_timeout 7d;
        }
        {% endif %}

So I'm changing the target of this issue to address only migration to Alpine.
