Feature: Added more documentation and clean code.

[werniq]

In this Pull Request, I have added a lot of documentation to functions and structs in the project, so that users can more easily understand what is going on.

Additionally, I made these additional changes:

• Renamed variables and funcs
• Reformatted Dockerfile
• Added more descriptive logging when error occurs + handled more errors.
• Implemented commands in Makefile to build/push docker image.
• Added taskfile (which In my opinion is more easy to read than Makefile, want the owner to verify it and if needed remove Make)
• Added ability for user to specify some key variables using flags, since some users may want to specify another port/network interface/etc.

I also would like to open Pull Request which integrates K8S to the project, but it contains updates from this PR. To not duplicate changes, I will do it after we resolve this PR.

Tbh I don't remember why I passed it there, you can remove it. Or, if you want to, you can implement some graceful shutdown on the application close for the sake of art 😄

[werniq]

Yes, I will. Probably by capturing signals. I guess I will do another PR with graceful shutdown.

[werniq]

It should be similar to this:

signal.Notify(quit, syscall.SIGINT, syscall.SIGTERM)

go func() {
        if err := srv.ListenAndServe(); err != nil && err != http.ErrServerClosed {
            log.Fatalf("Server failed: %s\n", err)
        }
    }()
log.Println("Server started on :8080")

<-quit
log.Println("Shutdown signal received, shutting down gracefully...")

ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
defer cancel()

if err := srv.Shutdown(ctx); err != nil {
        log.Fatalf("Server forced to shutdown: %s\n", err)
}

I love what you did here, for real man, great job. Just give me an answer if you will implement the graceful shutdown or not, and I will merge it 😄
