Web-based client for Kubernetes

Problem to solve

In order to interact with the Kubernetes API from the frontend (via KAS), we need a client of some sorts. Unfortunately, the official javascript client, kubernetes-client/javascript, does not support web browsers yet.

Proposal

• Create a project for the client under gitlab-org <-- @hfyngvason
• Generate the client using the javascript generator <-- @hfyngvason
• Publish the client in npm <-- @anna_vovchenko
• [-] Include it in package.json <-- @anna_vovchenko (will be done within the first frontend MR)

Evaluated options

A few options:

1. Port kubernetes-client/javascript to the browser. Start with a fork and then contribute the work upstream when we're happy with our results.
2. Chosen option: Wait for upstream to solve the problem. In the meantime, use an OpenAPI scaffold generated in a similar way to the Kubernetes client, i.e. using the typescript-fetch generator (docs), or maybe even just the javascript generator but without a dependency on node-fetch.
3. Wait for upstream to solve the problem. In the meantime, wrap the REST API calls we need on a case-by-case basis.

In the long run, I think (1) is the best solution, but starting with (2) or (3) would get us results faster.

I've prepared a PoC project for approach (2). This makes it possible to start building a real interactive web UI for Kubernetes without waiting for the KAS part to be finished.
