This switches us back to an approach where we use the Pod "exec" API to grab the keys we need, rather than forcing our code to run on the control plane node. It will help us fail gracefully (or dynamically switch to alternate implementations) when the cluster is not self-hosted.

- Add a unit test for each cert controller
- Make DynamicTLSServingCertProvider an interface and use a mutex
internally
- Create a shared ToPEM function instead of having two very similar
functions
- Move the ObservableWithInformerOption test helper to testutils
- Rename some variables and imports
The error was:
```
internal/certauthority/certauthority.go:68:15: err113: do not define dynamic errors, use wrapped static errors instead: "fmt.Errorf(\"expected CA to be a single certificate, found %d certificates\", certCount)" (goerr113)
return nil, fmt.Errorf("expected CA to be a single certificate, found %d certificates", certCount)
^
exit status 1
```
I'm not sure if I love this err113 linter.
I think we may still split this apart into multiple packages, but for now it works pretty well in both use cases.
