Mark Goddard b12f9e35e5 Performance: Parallelise Kolla Ansible host vars generation ... Kayobe generates a host_vars file for each host in the Kolla Ansible inventory. These contain network interfaces and other host-specific things. Currently this is done by iterating over all hosts, which does not scale well with a large number of hosts. This change extracts the host vars generation into a separate role, and executes it in a play targeted at all hosts, with delegate_to: localhost. This ensures that host variable files are generated in parallel. Story: 2007993 Task: 40629 Change-Id: Iae75e17024adee9c2874c14d3ed36f4c87ba48d7		2020-09-22 17:06:04 +01:00
