Currently websocket_call does some hackery to generate the websocket URL:

    # switch protocols from http to websocket
    url = url.replace('http://', 'ws://')
    url = url.replace('https://', 'wss://')

    # patch extra /
    url = url.replace('//api', '/api')

Websocket calls are broken when the URL includes the string 'api' in the hostname. For example:api.k8s.staging.mydomain.com will result in the following error:

kubernetes.client.rest.ApiException: (0)
Reason: hostname is invalid

A good solution would be to have proper URL parsing in place and replacing paths, rather than working off a pure string
