feat: add wsl support (Docker Desktop)

[e00dan]

1. In Docker Desktop enable "Expose daemon on tcp://localhost:2375 without TLS"
2. Find out your Host IP: https://docs.microsoft.com/en-us/windows/wsl/networking#accessing-windows-networking-apps-from-linux-host-ip
3. Run Windows PowerShell in Administrator mode and run:

netsh interface portproxy add v4tov4 listenport=2375 listenaddress=<YOUR_HOST_IP> connectaddress=127.0.0.1 connectport=2375

4. Create rule in Windows Defender Advanced Settings to open port 2375
5. Run curl http://<YOUR_HOST_IP>:2375/images/json in WSL to see if accessing remote Docker API works.
6. cargo build && DOCKER_API_URL=tcp://<YOUR_HOST_IP>:2375 ./target/debug/axon-cli

Works:

Are you running docker on Windows instead of WSL?
I tried this branch on Ubuntu 20.04 of WSL2 for Window10. And, I started docker on my WSL2. After running axon start command by axon-cli. I got the following error msg:

Error: error 400 Bad Request - create \wsl$\Ubuntu-20.04\root.axon/devtools: "\\wsl$\Ubuntu-20.04\root\.axon/devtools" includes invalid characters for a local volume name, only "[a-zA-Z0-9][a-zA-Z0-9_.-]" are allowed. If you intended to pass a host directory, use absolute path

If I run the main branch of axon-cli, it works fine.

Did you install Docker on WSL using https://www.docker.com/products/docker-desktop/ or did you install it in custom way?

I'm running Docker Desktop on WSL with exposed Remote API port from Windows host (it was unreachable otherwise)

I'm not sure cause I installed Docker long time ago.
But I didn't install Docker on my Win10 machine. Looks like I installed Docker for Ubuntu in custom way.
By the way, I'm using WSL2 instead fo WSL.
