Based on Odoo 15 - requirements are almost the same.

[skip ci]

With python 3.6, project does not install correctly without using a wheel build with python 3.7+

Only done on published branches, available manually on topics.

Extract version with setuptools-scm

The output directory is missing the branch name.

 use commit sha when building before test, so that it is already correctly expired by the base script

And also avoid sleep, just restart odoo after installing modules

Should parallel more steps

Also create target directories in docker_build_copy and update readme
