Use a local webserver for login

[aviaryan]

We will have to use negroni with negroni-sessions package for this.
Some SECRET variables need to be also introduced so we need to save them properly without making them visible to the end user.

Status update: Some changes have been implemented and pushed to feature/local-auth branch.

The authentication is working locally but the cookies generated are not sufficient to login into another server. Upon further inspection, it seems we are missing another component from AccAPI to be added into abc. That component may require database as well. So, local server login is getting unnecessarily complex. Maybe there exists a better way for this.
Holding this issue on pause for now.

Open sourcing will fail if we use this method. Hence closing.
