Refactor the kube-scheduler configuration API, command setup, and server setup according to the guidelines established in #32215 and using the kube-proxy refactor (#34727) as a model of a well factored component adhering to said guidelines. * Config API: clarify meaning and use of algorithm source by replacing modality derived from bools and string emptiness checks with an explicit AlgorithmSource type hierarchy. * Config API: consolidate client connection config with common structs. * Config API: split and simplify healthz/metrics server configuration. * Config API: clarify leader election configuration. * Config API: improve defaulting. * CLI: deprecate all flags except `--config`. * CLI: port all flags to new config API. * CLI: refactor to match kube-proxy Cobra command style. * Server: refactor away configurator.go to clarify application wiring. * Server: refactor to more clearly separate wiring/setup from running. Fixes #52428.
