This lets users specify params like "relative_priority" without
the operator needing to know about them.

The external zookeeper config was mostly a stub and most of the system
actually assumed internal management. Flesh out the support for external
management. Do the same for the database.
This also passes through any additional keys in the zookeeper and database
sections of the spec.

This switches from the ansible/dhall operator framework to kopf,
an operator framework written in pure Python. This allows us to:
* Build the operator application as a Python app.
* Build the operator image using the opendev python builder images.
* Run the operator as a Python CLI program "zuul-operator".
* Write procedural Python code to handle operator tasks (such as
creating new nodepool launchers when providers are added).
* Use Jinja for templating config files and k8s resource files
(direct pythonic manipulation of resources is an option too).
The new CR nearly matches the existing one, with some minor differences.
Some missing features and documentation are added in the commits
immediately following; they should be reviewed and merged as a unit.
Also, fx waiting for scheduler to settle in functional test since
we changed this log line in Zuul.
