Use docker in builds

[leVirve]

Maybe we can support docker in building environment?

Actually, I've done some experiment on dockerfile and docker-compose.

Somehow there's still some problems in MySQL container settings for non-ascii. :neutral_face: Even though, I think we should make a standard procedure for environment builds.

Here is my current effort on docker. With Django + MySQL + Nginx containers.

Finally I resolved the encoding issue in MySQL with a defined config under ./bin/nginx/mysql_charset.conf. And not sure how to config nginx, theres's a sample one under ./bin/nginx/nginx.conf. Any comment on it~
