Foad Lind b8f773a5ef feat: Make it possible to customize k8s resources
Currently there is no way for plugins to customize Kubernetes resources
defined in Tutor deployment manifests.
This change makes that possible by taking advantage of the strategic
merge patching mechanism in `kustomization.yml`.
Any resource definition in a `k8s-override` patch in a plugin will
override the resource defined by Tutor, provided that their names match.

Template patches
================
This is the list of all patches used across Tutor (outside of any plugin). Alternatively, you can search for patches in Tutor templates by grepping the source code::
git clone https://github.com/overhangio/tutor
cd tutor
git grep "{{ patch" -- tutor/templates
See also `this GitHub search <https://github.com/search?utf8=✓&q={{+patch+repo%3Aoverhangio%2Ftutor+path%3A%2Ftutor%2Ftemplates&type=Code&ref=advsearch&l=&l= 8>`__.
.. patch:: caddyfile
``caddyfile``
=============
File: ``apps/caddy/Caddyfile``
Add here Caddy directives to redirect traffic from the outside to your service containers. You should make use of the "proxy" snippet that simplifies configuration and automatically configures logging. Also, make sure to use the ``$default_site_port`` environment variable to make sure that your service will be accessible both when HTTPS is enabled or disabled. For instance::
{{ MYPLUGIN_HOST }}{$default_site_port} {
import proxy "myservice:8000"
}
See the `Caddy reference documentation <https://caddyserver.com/docs/caddyfile>`__ for more information.
