This model is used only to display the configuration to authorized
users. It's a TransientModel that dynamically creates the fields for
every odoo configuration parameter, environment variables and some
system ones. Before this change, each new parameter/variable will
create a field in database, which can lead to many issues (lot of
fields, field name too long). Storing the fields in a single JSON
field resolves these issues and is much cleaner anyway.
It's no longer supported in lxml:

* [IMP] load server environment options from odoo rcfile
This allows delivering the code with default configuration options for
all environments in the server_environment_file module, but letting
the administrator override some configuration entries in the regular
odoo configuration file.
* server_environment_file: update README
