Frontend: create authentication interface

[hexvolt]

Need to create a component for authentication. Implement the token authentication mechanism in the frontend app.
Implement functionality:

• Sign in
• Sign out

an interesting approach for sign up workflow: reduxjs/redux#297 (comment)

also to consider for managing forms later on: http://redux-form.com/7.0.3/

How do I disable csrf check when using Token Authentication? It is disabled already in DRF if the TokenAuthentication is on the first place. The issue was in the absence of trailing slash in the url, so that non-API Django view was triggered and, therefore, required a csrf token.

How to avoid long relative imports: add 'src' folder to the webpack.config.js:

resolve: {
    modules: ['src', 'node_modules', 'bower_components'],
    ....
