Simplify setup and pull secret flow with Red Hat SSO extension

[slemeur]

Goals

Thanks to the work done on the Red Hat SSO extension, we now would like to automate the process of getting the pull secret to start openshift local.

Sub-tasks

• Investigate API to gather the "pull secret" #201
• Implement pull secret retrieval through API and integrate into workflow #207

@jeffmaury I published @redhat-developer/rhaccm-client simplify it. The implementation for this feature should:

1. Add dependency Red Hat SSO extension
2. Ask for Red Hat SSO session through authentication API when configuring OpenShift Local Instance

const authSession: extensionApi.AuthenticationSession | undefined> = await extensionApi.authentication.getSession(
    'redhat.authentication-provider',
    ['api.iam.registry_service_accounts', //scope that gives access to hydra service accounts API
    'api.console', // scope that gives access to console.redhat.com APIs
    'id.username'], // adds claim to accessToken that used to render account label
    {createIfNone: true} // will request to login in browser if session does not exists
  );

3. get access_token from the session when created
4. call @redhat-developer/rhaccm-client to get pull_secret json string

import { AccountManagementClient } from '@redhat-developer/rhaccm-client';
const client = new AccountManagementClient({
  BASE: 'https://api.openshift.com/api/accounts_mgmt/v1',
  TOKEN: authSession.access_token,
});
const accessTokenCfg = await client.default.postApiAccountsMgmtV1AccessToken();
const pull_secret:string = JSON.stringify(accessTokenCfg);
