client.request should also return the statuscode

We often need a way to distinguish from CREATED, ACCEPTED, and OK as these often map to kube notions such as "configured", "created", "unchanged".

Document the common results in .create(), .replace() etc.

Have brute-forced this in. I'm assuming it's hideable by #23 for an easier interface.

Need to rethink this a bit for 0.8.0. The tuple is awkward in most cases. It seems that replace and create are the main users that can distinguish between OK/ACCEPTED/CREATED. Maybe think of something better for those?

delete_collection + delete is super weird: https://docs.rs/k8s-openapi/0.4.0/src/k8s_openapi/v1_13/api/apps/v1/deployment.rs.html
replace also acts on it:

pub enum DeleteNamespacedDeploymentResponse {
    OkStatus(crate::v1_13::apimachinery::pkg::apis::meta::v1::Status),
    OkValue(crate::v1_13::api::apps::v1::Deployment),
    Accepted(crate::v1_13::apimachinery::pkg::apis::meta::v1::Status),
    Unauthorized,
    Other,
}
pub enum DeleteNamespacedDeploymentResponse {
    OkStatus(crate::v1_13::apimachinery::pkg::apis::meta::v1::Status),
    OkValue(crate::v1_13::api::apps::v1::Deployment),
    Accepted(crate::v1_13::apimachinery::pkg::apis::meta::v1::Status),
    Unauthorized,
    Other,
}
pub enum CreateNamespacedDeploymentResponse {
    Ok(crate::v1_13::api::apps::v1::Deployment),
    Created(crate::v1_13::api::apps::v1::Deployment),
    Accepted(crate::v1_13::api::apps::v1::Deployment),
    Unauthorized,
    Other,
}
pub enum ReplaceNamespacedDeploymentResponse { // dittof for DeploymentStatus
    Ok(crate::v1_13::api::apps::v1::Deployment),
    Created(crate::v1_13::api::apps::v1::Deployment),
    Unauthorized,
    Other,
}

need to find appropriate kube docs to cross-reference..

OkStatus is actually not that weird! It's what we've called ApiError somewhat speculatively: https://github.com/kubernetes/apimachinery/blob/1f207b29b4411fb6ecfd342ae73fa60a921a5046/pkg/apis/meta/v1/types.go#L607-L638

By reading the api conventions doc we can see that it's actually returned on successful deletes as well! Although I've not actually seen an API call return that. Probably need some better tests.
