Document how to upgrade CPI using different installation method

[mczudowski]

There are 3 different installation methods described in the documentation:

• using deprecated manifests
• using release manifests
• using Helm chart

The problem is that each method provides DaemonSet configuration with different selector field, which is immutable.

I would like to provide up to date configuration for the https://github.com/kubernetes-sigs/kubespray repository, which still uses variation of deprecated manifests. It would be really helpful to know the recommended migration path.
