Build Odoo docker image from Debian package

The Dockerfile has been modified to use a local Odoo Debian package to install to the docker container.

Steps to build docker image

Fetch the odoo debian package from https://odoo.com/download
- for the enterprise version, you need to login to your Odoo account!
Rename the downloaded file to odoo.deb and place it in this directory.
Create the docker image my-odoo-15 with the following command:

docker build -t my-odoo-15 .

Use the docker image

The following docker-compose file will create three containers:

odoo15-web-live-1 --> the Odoo container itself
odoo15-db-live-1 --> the database (postgresql 13)
docker-odoo15-mailhog-1 --> mailhog instance
docker-odoo15-adminer-1 --> adminer instance
