Add release validation script, the script check for the following in order:

• The release branch: it makes sure that release branch matches the release tag version
• The kubernetes image tag: it makes sure that image tag matches the release tag version
• The kubernetes version: it makes sure that kubernetes version env variable matches the release tag version since its used in building both the runtime and windows runtime images as well as the test image
• The Kube-proxy version: it makes sure that kube proxy chart version matches the release tag version
• crictl and calico windows binaries: it makes sure that both binaries matches the Linux versions

At some point we're gonna need a shell package to source these types of things in since they're used in some many placed. No action. Just sayin... :)
