Cross CRDs checks for static routes overlapping #13

Background

It's very easy to create overlapping IPs/subnets across multiple CRDs, for same or different gateways.

Proposal

Have the controller logic check if same route is not managed by other CRDs, and deny the request if so.

Hint:

Maybe admission control is more appropriate, via validating webhooks.
