site-docker: ability to disable fact sharing
site-docker: ability to disable fact sharing

When deploying with Ansible at large scale, the delegate_facts method
consumes a lot of memory on the host that is running Ansible. This can
cause various issues like memory exhaustion on that machine.
You can now run Ansible with "-e delegate_facts_host=False" to disable
the fact sharing.
