Krzysztof Dryś f92e77f7f0 Remove legacy upgrade and it's references (#7309) ... With [linkerd2#5008](https://github.com/linkerd/linkerd2/issues/5008) and associated PRs, we changed the way configuration is handled by storing a helm values struct inside of the configmap. Now that we have had one stable release with new configuration, were no longer use and need to maintain the legacy config. This commit removes all the associated logic, protobuf files, and references. Changes Include: - Removed [`proto/config/config.proto`](https://github.com/linkerd/linkerd2/blob/main/proto/config/config.proto) - Changed [`bin/protoc-go.sh`](https://github.com/linkerd/linkerd2/blob/main/bin/protoc-go.sh) to not include `config.proto` - Changed [`FetchLinkerdConfigMap()`](741fde679b/pkg/healthcheck/healthcheck.go (L1768)) in `healthcheck.go` to return only the configmap, with the pb type. - Changed [`FetchCurrentConfiguration()`](741fde679b/pkg/healthcheck/healthcheck.go (L1647)) only unmarshal and use helm value struct from configmap (as a follow-up to the todo above; note that there's already a todo here to refactor the function once value struct is the default, which has already happened) - Removed [`upgrade_legacy.go`](https://github.com/linkerd/linkerd2/blob/main/cli/cmd/upgrade_legacy.go) Signed-off-by: Krzysztof Dryś <krzysztofdrys@gmail.com>		2021-11-29 20:08:58 +05:30
