create_admin ansible execution timesout when there are many network interfaces on a system

[Alex Schultz]

Similar to the issues we saw with puppet's facter, ansible also suffers when trying to run fact gathering on systems with many network interfaces. We see the create_admin workflow timeout due to the playbook taking too long because the fact gathering runs long. The create_admin tasks don't require any facts as the playbook is static so we should disable fact gathering

    Disable fact gathering for create_admin

    The create_admin execution doesn't require facts as the tasks are
    static. Fact gather can be a long time on systems with large number of
    network interfaces or storage volumes. This can lead to timeouts when
    doing actions like scaling or deploying.

[Bogdan Dobrelya (bogdando)]

It may be worth improving facts caching and/or tripleo-ansible's and t-h-t's gather_facts cases, like

and all that we have in tht common/deploy-steps.j2 and common/deploy-steps-playbooks-common.yaml
