Update auth-provider path

[russell]

Looks like after moving the backends, this path needs to be updated to be able to perform the relative import

using the code:

const Client = require('kubernetes-client').Client;
const Request = require('kubernetes-client/backends/request');
const backend = new Request(Request.config.fromKubeconfig());
const client = new Client({ backend, version: '1.13' });
await client.loadSpec();

i get this error

Error: Failed to get /openapi/v2 and /swagger.json: Cannot find module '../auth-providers/cmd.js'
