Replace request with undici

[danbev]

These commit replace request with undici.

---

Apart from the tests passing, a manual test was performed using:

First login using oc:

$ oc login
You must obtain an API token by visiting https://oauth-openshift.apps.sandbox.x8i5.p1.openshiftapps.com/oauth/token/request
$ oc login --token=<token>
Logged into "https://api.sandbox.x8i5.p1.openshiftapps.com:6443" as "dbevenius" using the token provided.

You have one project on this server: "dbevenius-dev"

Using project "dbevenius-dev".

Then run one of the examples from the README.md:

$ node - <<HERE
const openshiftRestClient = require('./index.js').OpenshiftClient;

openshiftRestClient().then((client) => {
  client.apis['project.openshift.io'].v1.projects.get().then((response) => {
    console.log(response.body);
  });
});
HERE
{
  kind: 'ProjectList',
  apiVersion: 'project.openshift.io/v1',
  metadata: {},
  items: [ { metadata: [Object], spec: [Object], status: [Object] } ]
}
