Fixes#4191#4993
This bumps Kubernetes client-go to the latest v0.19.2 (We had to switch directly to 1.19 because of this issue). Bumping to v0.19.2 required upgrading to smi-sdk-go v0.4.1. This also depends on linkerd/stern#5
This consists of the following changes:
- Fix ./bin/update-codegen.sh by adding the template path to the gen commands, as it is needed after we moved to GOMOD.
- Bump all k8s related dependencies to v0.19.2
- Generate CRD types, client code using the latest k8s.io/code-generator
- Use context.Context as the first argument, in all code paths that touch the k8s client-go interface

All of the code for the service mirror controller lives in the `linkerd/linkerd2/controller/cmd` package. It is typical for control plane components to only have a `main.go` entrypoint in the cmd package. This can sometimes make it hard to find the service mirror code since I wouldn't expect it to be in the cmd package.
We move the majority of the code to a dedicated controller package, leaving only main.go in the cmd package. This is purely organizational; no behavior change is expected.
