Subject: [PATCH] Add multi_coop configuration via environment variable in
 docker setup

If the file app_config.defaults.yml exists in the working directory,
the content will be written to the config/app_config.yml and appended
by a configuration entry for every foodcoop in the space separated
environment variable FOODSOFT_FOODCOOPS.
