Add support for querying TrafficSplit resources through the common API layer. This is done by depending on the TrafficSplit client bindings from smi-sdk-go.

Numerous codepaths have emerged that create k8s configs, k8s clients,
and make k8s api requests.
This branch consolidates k8s client creation and APIs. The primary
change migrates most codepaths to call `k8s.NewAPI` to instantiate a
`KubernetesAPI` struct from `pkg`. `KubernetesAPI` implements the
`kubernetes.Interface` (clientset) interface, and also persists a
`client-go` `rest.Config`.
Specific list of changes:
- removes manual GET requests from `k8s.KubernetesAPI`, in favor of
clientsets
- replaces most calls to `k8s.GetConfig`+`kubernetes.NewForConfig` with
a single `k8s.NewAPI`
- introduces a `timeout` param to `k8s.NewAPI`, currently only used by
healthchecks
- removes `NewClientSet` in `controller/k8s/clientset.go` in favor of
`k8s.NewAPI`
- removes `httpClient` and `clientset` from `HealthChecker`, use
`KubernetesAPI` instead

The control-plane's clients, specifically the Kubernetes clients, did
not provide telemetry information.
Introduce a `prometheus.ClientWithTelemetry` wrapper to instrument
arbitrary clients. Apply this wrapper to Kubernetes clients.

Commit 1: Enable lint check for comments
Part of #217. Follow up from #1982 and #2018.
A subsequent commit will fix the ci failure.
Commit 2: Address all comment-related linter errors.
This change addresses all comment-related linter errors by doing the
following:
- Add comments to exported symbols
- Make some exported symbols private
- Recommend via TODOs that some exported symbols should should move or
be removed
This PR does not:
- Modify, move, or remove any code
- Modify existing comments

This commit removes duplicate logic that loads Kubernetes config and
replaces it with GetConfig from pkg/k8s. This also allows to load
config from default sources like $KUBECONFIG instead of explicitly
passing -kubeconfig option to controller components.

We’ve built Conduit from the ground up to be the fastest, lightest,
simplest, and most secure service mesh in the world. It features an
incredibly fast and safe data plane written in Rust, a simple yet
powerful control plane written in Go, and a design that’s focused on
performance, security, and usability. Most importantly, Conduit
incorporates the many lessons we’ve learned from over 18 months of
production service mesh experience with Linkerd.
This repository contains a few tightly-related components:
- `proxy` -- an HTTP/2 proxy written in Rust;
- `controller` -- a control plane written in Go with gRPC;
- `web` -- a UI written in React, served by Go.
