Reimplementation in Go, fix #1

[HorayNarea]

I couldn't help it, it just seemed to be so much fun… 😁

Of course, this is just a proposal. If you think something is wrong or you don't like the idea of building it in go just tell me, I won't be mad :)

It's a fix for #1 because:

• RAM-Usage: 3-5 MB instead of >30 MB
• Docker-Imagesize: ~250 MB instead of >600 MB
• minimal size (compiled to a single binary): <6 MB

and all that while it's really fast and more flexible and a bit more modular. Yay!

PS: having the dependencies vendored is best-practice in go and I'm not using git-submodules because then it can't build if the initial repo is gone or GitHub has hickups

Huh, this is amazing :) thank you so much for contributing. I definitely agree with implementing this in Go, and would even like to go further.

I guess, I will have to learn Go in the next few weeks. I see no reason to maintain the Python version anymore, even if this is not the final form, so let's go.

You're welcome! 😊

On the "would even like to go further": learning Go and building a bit more of Mailu in it? 😉
If so: I would like to help you very much, with both!

Mmmh, its more of a discussion for our chat channel, but: currently the admin is written in Python and moving to Go would be a huge job. Maybe we could consider it for version 2.0 because that project still requires rewriting most of the admin container.

I am still concerned about completely switching technologies. So, well. Not sure, but it is an option to consider.
