#7161 feat: add Knative serving dependency and app service config structs Pull request opened by AdilFayyaz Why are the changes needed? The App Service needs to manage Knative KService CRDs to deploy and stop long-running apps. This PR lays the foundational infrastructure — dependency, scheme registration, and config — that subsequent PRs will build on. What changes were proposed in this pull request? • Add knative.dev/serving v0.40.2 (pinned to a version compatible with the repo's existing k8s.io v0.28.x constraints) • Add actions/k8s/app_scheme.go: InitAppScheme() registers KService, Route, Configuration, and Revision types into the client-go scheme so the K8s client can work with KService CRDs • Add AppConfig to actions/config: feature flag, KService namespace, and request timeout bounds • Add AppsConfig to runs/config: public URL pattern template and internal app service URL for the control-plane proxy • Moved the files in app/ to flytestdlib/ and respectively the call sites as well How was this patch tested? • go build ./actions/... ./runs/... passes with no errors • go mod tidy is clean with no missing or unused dependencies • Existing packages that use golang-lru (upgraded v0.5.4 → v1.0.2 as a transitive side effect) were verified: go build ./flytestdlib/... ./flyteplugins/... passes — v1.x preserves the non-generic API used by this repo Setup process Screenshots Check all the applicable boxes • I updated the documentation accordingly. • All new and existing tests passed. • All commits are signed-off.
