* First hack at getting the namespaces of interest to the ps
* Have the webhook label the namespace for inclusion
* Fix unit tests
* Update with feedback
* Add namespace lister, use constants
* Add one more err logging statement
* add ability to opt-out of bindings
* I guess a year changed...
* had opt-in / opt-out backwards
* add unit test for contexts, fix comment
* clarify comments
* remove Binding from method/const names since already in bindings package
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.
