Resolve: Facilitate local development

[brendangadd]

• Add Azure auth support to API server
• Proxy front-end API calls to local API's default port
• Stop front-end from unnecessarily polling namespaces
• Use text field for active namespace when front-end not hooked up to
  the central dashboard
• Stop namespace service from defaulting to "kubeflow" namespace

Closes #2

From running go run . -spawner-config samples/spawner_ui_config.yaml from project root, these errors appear:

From front-end folder, running npm install and KF_USER_ID=<your_cloud_account> npm start with my cloud account, these errors appear:

subjectaccessreviews.authorization.k8s.io is forbidden: User "saffa.alvi@cloud.statcan.ca" cannot create resource "subjectaccessreviews" in API group "authorization.k8s.io" at the cluster scope

Most likely due to not having the required level of k8s permission, so it isn't letting the API server hydrate its cache of the referenced resources

[saffaalvi]

Steps taken to test this:

1. kubectl setup
2. install Go
3. From project root, run . -spawner-config samples/spawner_ui_config.yaml
4. From front-end folder, npm install and KF_USER_ID=<your_cloud_account> npm start

After step 4, open browser to http://localhost:4200/jupyter/, update namespace, everything works fine and no errors.

[wg102]

My only comment would be to add some documentation about how to set it up, the 4 steps we need, and possibly also the necessary permissions for other future users.

@wg102 Good point. I'd usually block this PR to address your comment, but these changes are currently aimed at you and @saffaalvi and you both know how to run it. So I created #10 to do this in a separate PR.
