Allow provided templates to be extended through template inheritance

[oxyc]

Trellis has a convention of splitting complicated Jinja2 templates into separete blocks that can be inherited in child templates.

Eg. their nginx vhost template https://github.com/roots/trellis/blob/master/roles/wordpress-setup/templates/wordpress-site.conf.j2

I see that this has been merged, but I still have a question relating to this.

How can I override the template for each individual host?
I'm new to child templates, so maybe this is a silly question, if so, sorry!

Say I have 3 sites in my installation, how can I easily have 3 completely different vhost configurations for them?

The way I do it in my personal roles is something like this:

nginx_sites:
  - name: "My Site 1"
    server_name: site1.example.com
    template: "site1.example.com.site.j2"
  - name: "My Site 2"
    server_name: site2.example.com
    template: "site2.example.com.site.j2"
  - name: "My Site 3"
    server_name: site3.example.com
    template: "site3.example.com.site.j2"

Being able to do something like this would be really great!

I've started using this role for a different project, putting everything in the nginx_vhosts.extra_parameters variable which just isn't very pretty and bloats everything.

Thanks!

I like it! Opened up a PR if @geerlingguy does too.
