When Kolla Ansible is executed with a '--limit' argument, the scope of an operation is limited to the hosts in the limit. For example: kolla-ansible deploy --limit control Due to the nature of configuring clustered software services, there are cases where we need to know information about other hosts. Most often this is related to their hostname or network addresses. To make this work, Kolla Ansible gathers facts for hosts outside of the limit using delegated fact gathering [1]. By default, Kolla Ansible gathers facts for all hosts. Because delegated facts are gathered serially in batches by the active hosts, this can take a long time when there are not many hosts in the limit. This change makes it possible to reduce the set of hosts eligible for delegated fact gathering by setting 'kolla_ansible_delegate_facts_hosts' to a list of hosts.
