Remove deprecated npm request dependency

[WassimBenzarti]

Describe the bug
There is a vulnerability related to request npm package which is a dependency of @kubernetes/client-node. Here’s the npm audit report:

# npm audit report

request  *
Severity: moderate
Server-Side Request Forgery in Request - https://github.com/advisories/GHSA-p8p7-x288-28g6
No fix available
node_modules/request
  @kubernetes/client-node  *
  Depends on vulnerable versions of request
  node_modules/@kubernetes/client-node

2 moderate severity vulnerabilities

Some issues need review, and may require choosing
a different dependency.

Unfortunately, the GitHub repository is not currently maintained and there are no maintainers who could merge this PR.

Is there any chance we can remove the request dependency since it’s deprecated since February 2020.

This is currently work in progress and the current state is in the release-1.x branch.
There is a tag published in the current state but I think it's not yet officially supported and doesn't include all features:
1.0.0-rc1
