support remaining Kustomize flags

[nazarewk]

Basically I need to run a custom KRM exec to fix the deployment and need some of those flags to make it work, at the same time I've added rest of the flags.

• checked working with dev_overrides
• releasing as https://registry.terraform.io/providers/nazarewk-iac/kustomization (still building)
• docs update

Generally the change LGTM. But please take a look at my comment regarding the changes to the gpg action and keep it separate from this PR.

Thanks for your contribution.
