In odoo/documentation-user#945, the developer documentation is merged
with the user documentation in a single repository and build config.

This commit then removes source files for the developer documentation
from the odoo/odoo repository.

In some situations it is important to protect the Odoo service from
direct access from the internet, or to protect internal network
resources from the Odoo server itself.

This is heavily dependent on deployment requirements, and for standard
installations on a public cloud system, this may not be necessary.
Yet it seems useful to mention it in the deployment recommendations,
as it may not be obvious to our users.

Our thanks to Ameya Darshan for raising this concern!
