Create CRD validation specs in CRD manifests and as Go code (#869)
* commands/.../generate/*: build and call openapi-gen, and re-scaffold CRD manifests
commands/.../add/api.go: call OpenAPI generator function
pkg/scaffold/crd*: use CustomRenderer interface to write CRD manifests
with validation spec instead of a template
pkg/scaffold/gopkgtoml*: include openapi-gen deps
pkg/scaffold/types*: add openapi-gen directives
* fix comment
* only use controller-tools CRD generator if in a Go project
* change dir in unit test so Go project is detected
* add names and only overwrite dstCrd when a file at path was generated
remove status field from resulting struct
* use generated crd if one isn't present locally
* add test case for non-Go crd generation
* internal/util/*util/*: remove pkg/scaffold imports, which cause cycles
* test/e2e/memcached_test.go: symlink pkg and internal
* pkg/scaffold/*: use a testData dir for scaffold tests instead of test/test-framework
* rename test dir to avoid import cycles during e2e test
* pkg/scaffold/crd.go: add IsOperatorGo field for controller-tools crd generator condition
* use test/test-framework code as test project
* revert removing scaffold constants from internal/util
* revert SrcDir change and check IsOperatorGo first
* change function name
* pkg/scaffold/crd.go: simplify unmarshalling crd
* use Golang initialism/acronym conventions for naming CR(D) types/variables
* Gopkg.lock: revendor
* commands/.../openapi.go: return error from CLI func instead of log.Fatal
* fix kube-openapi revision
* pkg/scaffold/gopkgtoml*.go: force sigs.k8s.io/controller-tools/pkg/crd/generator vendoring
* remove extra kube-openapi override
* pkg/scaffold/types*.go: add note on adding custom validation
* commands/.../api.go: comment on what is generated in add api command usage
* commands/.../openapi.go: remove go header file from openapi-gen
* new() -> &...{}
* correct verbosity settings for deepcopy and openapi generators
* commands/operator-sdk/cmd/add/crd.go: only skip overwriting CRD's/CR's if explicitly adding them
* verbose code generation in e2e test
* add --header-file for Go boilerplate file path
* update openapi command comment
* override go-openapi/spec to avoid new project dep solve errors
* revendor- Loading branch information
