* If an excpetion occurs during the main loop, the builder crashes. With
this commit, the main_loop is in a try/catch.
Also:
* remove unused imports
* move the first log after the Odoo import because Odoo changes the
process timezone to UTC
Actually, when deploying multiple instances of runbot, a full odoo
installation is needed.
With this commit, a single standalone (sort of) can be used to start a
runbot builder. It uses the same database as the runbot scheduler.
This script just reserve pending builds for himself and starts to build.
This is just a proof of concept. It should work alongside with a
standard runbot installation.
