This PR adds facilities to make it easier to create both components of a Binding
over "Pod Spec"-able resources. Rather than rehashing it all here, please look
at `./pkg/webhook/psbinding/README.md` for more details.
I'm splitting this off of another change that needed them, the three changes are:
1. Give the PostConditions callbacks in TableRow access to the Reconciler
resource. It turns out this is incredibly useful to have the `TableRow`
program an admission controller and then test that programming by calling
`Admit()`.
1. Surface the test resources in our webhook "listers", and add the testing
scheme.
1. Change the `objKey` to only use reflection as a fallback. The existing logic
doesn't work properly when a mix of real resources and unstructured.Unstructured
is used for the same resource.
* Create a new singleton Reconciler for the webhook secret.
This change creates a new Reconciler (not yet hooked up) that ensures that the
webhook secret has the appropriate shape. I call this a "singleton Reconciler"
because this reconciler exists to effectively reconcile a single resource, which
will be a pattern for the webhook's reconcilers.
* Address linter problems
This pulls the Knative webhook logic (oriented around the interfaces in `knative/pkg/apis`) into `knative/pkg`.
The code is largely copied as-is, with `keep.go` excluded. The main changes are to the test code, which in `knative/serving` still operate in terms of the serving types.
