resource is up and running but found an edge case in the docs

When a port is defined with a nil port value, it indicates "all ports".

also setting the limits on how many ports and addresses a user can set.

When a port is defined with a nil port value, it indicates "all ports".

This is tricky because the number type doesnt differentiate between 0 and empty, but 0 is a valid value to send for port. We will have to change this attribute to be a string and if the value is "" don't set it in the request payload.

I had to also change app_protocol from Optional to Required due to this error that I came across:

│ Error: Failed to create endpoint_slice because: EndpointSlice.discovery.k8s.io "test" is invalid: [ports[0].appProtocol: Invalid value: "": name part must be non-empty, ports[0].appProtocol: Invalid value: "": name part must consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyName',  or 'my.name',  or '123-abc', regex used for validation is '([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9]')]
│ 
│   with kubernetes_endpoint_slice_v1.test,
