Add support for additional query parameters in kustomize resource URLs.

Kustomize allows the following query string parameter in it's remote resource URLs:

- ref
- version
- timeout
- submodules

(refer to https://github.com/kubernetes-sigs/kustomize/blob/master/examples/remoteBuild.md for full description)

This makes renovate aware of these and allows to correctly extract the current version in case more parameters are being used by the end-user.
