This commit creates a new version of the alpha configuration functions framework. Goals include:
- Make it easy to build multi-version APIs with the framework (not previously facilitated at all).
- Simplify the framework's APIs where redundant configuration options exist (leaving the most powerful, replacing others with helpers to maintain usability they provided).
- Make the Framework's APIs more consistent (e.g. between the various template types, usage of kio.Filter, field names)
- Decouple responsibilities (e.g. command creation, resource list processing, generation of templating functions).
- Make the framework even more powerfully pluggable (e.g. any kio.Filter can be a selector, and the selector the framework provides is itself a filter built from reusable abstractions).
- Improve documentation.
- Make container patches merge fields (notably list fields like `env`) correctly.
This is the last commit in yaml.v3 before
ae27a74434
which changed the indentation of sequence.
That change has has large downstream impact on tests in the kustomize
repo. To upgrade beyond this point in yaml.v3 means many changes to
indentation in "expected" values in tests. That should be done in a
PR dedicated to that purpose, after specific consideration the change.
