Yehonal 380f406248 Feat(Docker/bash): docker-compose system rework (#4488)
## ⚠️ATTENTION! ⚠️ Upgrading procedure:

**Database:** After this PR will be merged you need to backup your DB first (you can use the db-assembler or any mysql client to generate the dump) and restore it after.  The reason is that we use now docker named volumes instead of binded ones to improve performance.

**Conf & client data**: if you use the default configuration, both the etc and the data folder are now available inside the **/env/docker**. 

Finally, you can cleanup the /docker folder previously used by our system.

## Changes Proposed:

This PR will implement the [devcontainer ](https://code.visualstudio.com/docs/remote/containers) feature for VSCode. Allowing us to develop and debug directly within the container in the same way on all OSes.

* Implemented support for vscode dev-container feature by remote-extension suite
* Docker performance optimizations for MacOS and non-linux hosts
* Bash system improvements
* Implemented first command using Deno runtime environment (typescript) and [commander.js]
* Implemented wait mechanism for db_assembler
* Implemented db migration command
* possibility to run the authserver and worldserver with GDB using the integrated simple-restarter
* Implemented docker multi-stage mechanism to use one single Dockerfile for all the services
* client-data downloader now creates a placeholder to avoid downloading the same version of data files multiple times
* deployment of pre-compiled docker images on [docker hub](https://hub.docker.com/u/acore), you can test them [here](https://github.com/azerothcore/acore-docker)
