Headless app fix

Fix default class names

Docs had been created without a plugin that renames the default
exports, so a lot of classes were names as default.

This patch uses the "typedoc-plugin-rename-defaults" package which
renames the default exports, otherwise e.g. classes that are part of
the lib/k8s modules would be exported as simply "default".

Plugin changes

Bundled app plugins

frontend: Add networkpolicy API

We would be needing the networkpolicy API for the security advisor
plugin. This patch adds the required API for it.

Allow listing resources per namespace

Allow to easily set sidebar icons

There was an issue sometimes when trying to run one of the eslint
commands from "lint-staged" as it would find two versions of its
plugins (both from frontend/ and from the example plugins), so we
add an option to indicate that plugins should be resolved against
the current directory.

There was no way to set an icon to the sidebar items, so this patch
allows that as part of the "opts" argument of the mentioned method.

backend: Add no-cache header for plugins when running in desktop

Since users may not have permissions to list resources on certain
namespaces, we now allow passing an options object that allows using a
namespace to filter resources.

When running in the desktop, there is no big advantage to allowing the
plugins to be cached, and we have hit issues where the plugins were
being cached while the user is attempting to reload them (for
development). So this patch prevents that by adding a no-cache header
to the /plugins/ request responses.

Generate more type documentation

Export all k8s modules

These changes target all warnings from the typedoc generation,
exporting the needed interfaces and specifying also a new
ConfigAction interface, so all warnings are covered.
