I learned a neat trick in Go

I learned a neat trick in Go.

I have a VERSION file at the project root holding the current version number of DiceDB. I want to use this version everywhere I am referring to the version

1. when the server runs
2. version subcommand
3. tests, and
4. even baked in the binary

Instead of duplicating the version across the codebase, here’s an interesting hack using the current caller (check screenshot).

This, combined with the build-time injection of version variables, makes sure that even the binary has access to this version number without having to ship the VERSION file everywhere [that’s impactical anyways].
