Clarify a few variable names, make code more modular. Also, the Renderer
class now makes more sense as a singleton. We took the opportunity to
delete quite a lot of code.
This has an impact on plugin hooks. Plugin hooks that needed to run
inside mysql-client now need to run inside mysql container. This
simplifies the deployment, as we no longer have an empty mysql-client
container sitting around.
When mysql is not enabled (ACTIVATE_MYSQL=False) the mysql container is
simply a mysql client.
This commit introduces many changes:
- a fully functional minio plugin for local installation
- an almost-functional native k8s deployment
- a new way to process configuration, better suited to plugins
There are still many things to do:
- get rid of all the TODOs
- get a fully functional minio plugin for k8s
- add documentation for pluginso
- ...
Configuration loading was overly complex. Here, we simplify it
drastically with reasonable defaults. Hacky additional variables are
unncessary now that we use custom jinja2 filters.
