User Story

As a user I would like to use a common provider version variable as capi, controlPlane and Kubeadm provider versions are usually the same.

Detailed Description

As a user, I have to pass the same version(Eg. 1.6.1) in 3 places to install a specific version of core, controlplane, kubeadm providers. Usually, all 3 provider versions are the same.

CAPI Operator Helm chart should support a common version that all 3 providers can use. If a common version is not found, provider-specific versions can take precedence.
