Authorization+Authentication service in Golang

Created this project for HousewareHQ-github-octernship. My design decision was pretty simple as I created golang project for the first time. In the beginning I was pretty confused while thinking about folder structure for this project. So I just tried my best. Thanks. Ps :- Sorry for the Github Flow avoidation, was working on local-repo and commited the whole project on last day in this repo.
