CustomResource derive; allow status attribute to take a path

[clux]

fix for #1703

allows module gated imports to be referenced such as;

pub mod mystatus {
    use super::*;
    #[derive(Debug, Clone, Serialize, Deserialize, PartialEq, JsonSchema)]
    pub struct FooStatus { ... }
}

by using #[kube(status = "mystatus::FooStatus")] on a spec struct.
