Create new webhooks with kubebuilder

Since we use a non standard (according to kubebuilder) repo structure, kubebuilder commands won't work. For this purpose, we have a script that temporally changes our folder structure to one that kubebuilder understands and restores the original one after executing the kubebuilder command.

Example

./hack/kubebuilder.sh create webhook --group anywhere --version v1alpha1 --defaulting --programmatic-validation --kind WhateverKind

--defaulting creates mutation webhooks and --programmatic-validation creates validation webhooks.

Change webhook marker name to under anywhere.amazonaws.com

The default name in webhook marker is v<kind>.kb.io, we need to change it to <validation/mutation>.<kind>.anywhere.amazonaws.com
