Use kopf operator framework

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.

{- This file provides a central `Prelude` import for the rest of the library to
use so that the integrity check only needs to be updated in one place
whenever upgrading the interpreter.
This allows the user to provide their own Prelude import using the
`DHALL_PRELUDE` environment variable, like this:
```
$ export DHALL_PRELUDE='https://prelude.dhall-lang.org/package.dhall sha256:...'
```
Note that overriding the Prelude in this way only works if this repository
is imported locally. Remote imports do not have access to environment
variables and any attempt to import one will fall back to the next available
import. To learn more, read:
* https://docs.dhall-lang.org/discussions/Safety-guarantees.html#cross-site-scripting-xss
This file also provides an import without the integrity check as a slower
fallback if the user is using a different version of the Dhall interpreter.
This pattern is documented in the dhall-nethack repo:
* https://github.com/dhall-lang/dhall-nethack/blob/master/Prelude.dhall
