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.

This module was not implemented in the same nature as the others
since it needed to be instanced in order to be used, but most methods
are static in the base class.

Instead of using this customresource module, the
makeCustomResourceClass method from crd should be used.

The reason for this is that we use the module in lowercase inside
Headlamp's source code, so plugin developers may also do that by
copying. This way we may avoid misunderstandings.

These modules can be very helpful for plugin developers, so we should
expose them.

backend: Fix plugins path on windows

If a plugin chooses to use text or an icon to override Headlamp's logo,
it'd be shown in a dark color which is impossible to see on the
sidebar's black background. This patch makes that icon/text color be
the theme's contrast text color to avoid this.

backend: Encode state in base64, use this rather than plain cluster name

The OIDC state is used for verifying the incoming OIDC callback requests
 and we should make sure it's transmitted without issues, regardless of
 its value, so this patch starts using that state in encoded in base64.
 This also fixes an issues related to the state's length, as it needs
 to be longer than 8 chars, and this new base64 encoding grants that
