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.
