✨ feat: Write cli executable as a go program (#4)

## Description

**What issue are you solving (or what feature are you adding) and how
are you doing it?**
I have opted to go with Golang as it has inbuilt support for writing
cross-platform executables unlike something like JS. And also, it has
support for running docker using the unix socket directly in code.
