Deploy - Unable to docker compose emqx

[rapcmia]

When setting up source for testing PR18, we have to use docker compose. up emqx for running the hummingbot-broker however it requires to manually add .env file which is created from bash setup.sh

Workaround: Manually create .env file below:

CONFIG_PASSWORD=a
BOTS_PATH=insert-directory-of-deploy

Steps to reproduce:

1. Clone https://github.com/hummingbot/deploy
2. Run docker compose up emqx -d

this is not the expected way to use the project, that's why we have a setup.sh
