This moves the common Condition stuff to apis, and creates a v1beta1 form of Status that uses the Condition it defines (changing this in v1alpha1 is too breaking).
There aren't really any meaningful changes in this PR, mostly reorganization. Enumerating what I did:
1. Copied `condition_set*.go` to `apis/`,
1. Copied the `Condition` portions of `conditions_types.go` to `apis/`,
1. Copied the balance of `conditions_types.go` to `apis/duck/v1beta1/status_types.go`,
1. Changed the parts of the above to reference things in the appropriate new places,
1. Removed the reflection-based `ConditionsAccessor` stuff, implementing it instead on `duckv1beta1.Status`.
1. Incorporate: https://github.com/knative/pkg/pull/358
* fix very annoying logging in the integration tests
* Add clean test loggers method.
This would help us run the tests over-and-over again.
Currently the test hogs `t` and that object is not reusable.
This adds a logkey.Key for attaching the key being reconciled to a logger we embed into the context passed to Reconcile. The point of this is to enable us to eliminate [this](928d580756/pkg/reconciler/v1alpha1/service/service.go (L101-L104)) boilerplate from each of the Reconcilers.
These aren't identical, this has the form:
knative.dev/key: foo/bar
What it's replacing has the form:
knative.dev/namespace: foo
serving.knative.dev/service: bar
However, the type information present in the latter is redundant with the controller type that [should already be embedded](928d580756/pkg/reconciler/reconciler.go (L80)) in the logger.
