Hydration Logic

The hydrate subcommand is an helper to fill kustomization configuration files with resources and patches.

For doing so without launching multiple commands with different parameters, and leaving the user being able to add specific patches that needs custom targeting will only add files that conform to specific regex and we will skip files that are already present in the relative section in the file.

The first regex will match any file that ends with .patch.yaml or .patch.yml and the files patch.yaml and patch.yml. These files will be assumed that they contains a strategic-merge-style patch and they will be added to the patches section of the kustomize file.

The other regex will match every file that has the yaml or yml extensions that has not been matched in the previous regex.
These files will be added to the resources section.
