allow customising certain list parameters

[clux]

Not sure how much we actually need to expose, but dropping down some notes:

An initializer controller should list and watch for uninitialized objects, by using the query parameter ?includeUninitialized=true. (Kubernetes Initializers Deep Dive)

maybe timeoutSeconds if wanting to poll more frequently than every 10s?

It also makes sense to have stuff like field_selector values passed in.

There's a bit of common ground in optional structs like:

• ListNodeOptional
• ListPodOptional
• ListDaemonSetOptional
• ListIngressOptional
• ListDeploymentOptional

and similarly

• WatchPodForAllNamespacesOptoinal

etc. Given that we already keep track of resource_version, discard pretty, encapsulate timeout_seconds, hide, limit it might just make sense to include a common options struct:

#[derive(Default)]
struct QueryOptions {
    field_selector: Option<String>,
    include_uninitialized: Option<String>,
    label_selector: Option<String>,
    timeout: Option<u32>
}

have the informers, reflectors take options as a third arg:

let inf : Informer<NodeSpec, NodeStatus> = Informer::new(client,  ResourceType::Nodes, QueryOptions::default())

[clux]

Rather than having a third parameter. We've made a builder pattern for the option and flattened it into Informer and Reflector (for now).
