Add Dockerfile and Compose file

[chris-crone]

This requires a version of Docker with Wasm WASI support to work.

Steps to test:

1. Run docker compose up
2. Run docker run --rm --network host curlimages/curl curl http://0.0.0.0:8080/init to initialize

Running docker run --rm --network host curlimages/curl curl http://0.0.0.0:8080/init to initialize the DB, the Wasm service is panicking:

Any ideas @juntao @CaptainVincent ?

Hmm, we had this problem with the MySQL Docker image too ...

Our CI installs Unbuntu's default MySQL-server 8.0.30 and it works well. Can you try an image with that version?

My guess is that the mysql_common crate had an issue that has not been updated.

Same issue with mysql:8.0.30 but works with mariadb:10.9 so I'll use that.

I also added some examples to the README to show how to use a dockerized curl.
