Helm chart for cloud provider

[CecileRobertMichon]

What would you like to be added:

A Helm chart for installing CCM and CNM. Example of another project doing something similar: https://github.com/cilium/cilium/tree/v1.11.1/install/kubernetes/cilium

Why is this needed:

Now that external cloud provider is becoming the default in future versions of Kubernetes, we need to provide users an easy way to install and upgrade their cloud provider components. Because there is such a strict dependency between cloud provider version and Kubernetes version (see version matrix in https://github.com/kubernetes-sigs/cloud-provider-azure#current-status), this requires users to manually check that their version of Kubernetes is compatible with their version of cloud-provider. A Helm chart would allow us to benefit from the kubeVersion field to define k8s version constraints instead having to deal with those manually. It would also make upgrading the version of cloud provider along with k8s version easier and make sure cloud provider users aren't running old versions in their clusters, making them less likely to run into bugs.
