build: move e2e dependencies into e2e/go.mod

Several packages are only used while running the e2e suite. These
packages are less important to update, as the they can not influence the
final executable that is part of the Ceph-CSI container-image.

By moving these dependencies out of the main Ceph-CSI go.mod, it is
easier to identify if a reported CVE affects Ceph-CSI, or only the
testing (like most of the Kubernetes CVEs).

# cloud-provider
This repository defines the cloud-provider interface and mechanism to initialize
a cloud-provider implementation into Kubernetes. Currently multiple processes
use this code although the intent is that it will eventually only be cloud
controller manager.
**Note:** go-get or vendor this package as `k8s.io/cloud-provider`.
## Purpose
This library is a shared dependency for processes which need to be able to
integrate with cloud-provider specific functionality.
## Compatibility
Cloud Providers are expected to keep the HEAD of their implementations in sync
with the HEAD of this repository.
## Where does it come from?
`cloud-provider` is synced from
https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/cloud-provider.
Code changes are made in that location, merged into k8s.io/kubernetes and
later synced here.
## Things you should NOT do
1. Add an cloud provider specific code to this repo.
2. Directly modify anything under vendor/k8s.io/cloud-provider in this repo. Those are driven from `k8s.io/kubernetes/staging/src/k8s.io/cloud-provider`.
3. Make interface changes without first discussing them with
sig-cloudprovider.

package names
// Canonical controller names
//
// NAMING CONVENTIONS
// 1. naming should be consistent across the controllers
// 2. use of shortcuts should be avoided, unless they are well-known non-Kubernetes shortcuts
// 3. Kubernetes' resources should be written together without a hyphen ("-")
//
// CHANGE POLICY
// The controller names should be treated as IDs.
// They can only be changed if absolutely necessary. For example if an inappropriate name was chosen in the past, or if the scope of the controller changes.
// When a name is changed, the old name should be aliased in CCMControllerAliases, while preserving all old aliases.
// This is done to achieve backwards compatibility
//
// USE CASES
// The following places should use the controller name constants, when:
// 1. registering a controller in app.DefaultInitFuncConstructors or sample main.controllerInitializers:
// 1.1. disabling a controller by default in app.ControllersDisabledByDefault
// 1.2. checking if IsControllerEnabled
// 1.3. defining an alias in CCMControllerAliases (for backwards compatibility only)
// 2. used anywhere inside the controller itself:
// 2.1. [TODO] logger component should be configured with the controller name by calling LoggerWithName
// 2.2. [TODO] logging should use a canonical controller name when referencing a controller (Eg. Starting X, Shutting down X)
// 2.3. [TODO] emitted events should have an EventSource.Component set to the controller name (usually when initializing an EventRecorder)
// 2.4. [TODO] registering ControllerManagerMetrics with ControllerStarted and ControllerStopped
// 2.5. [TODO] calling WaitForNamedCacheSync
// 3. defining controller options for "--help" command or generated documentation
// 3.1. controller name should be used to create a pflag.FlagSet when registering controller options (the name is rendered in a controller flag group header)
// 3.2. when defined flag's help mentions a controller name
// 4. defining a new service account for a new controller (old controllers may have inconsistent service accounts to stay backwards compatible)
// 5. anywhere these controllers are used outside of this module (kube-controller-manager, cloud-provider sample)
