[ADD] docker file and shippable compatibility

Docker odoo image
Building here
[ocaimages/oca-odoo](https://registry.hub.docker.com/u/ocaimages/oca-odoo/builds_history/91750/)
I don't add ```depth=1 single-branch``` because I want re-use this folder to future builds don't download mqt from scratch in each build.
(If folder exists then ```git fetch```, same case with odoo folder)
(This is the second PR when this is meged)
