As per BZ#1438294, update the docs to reflect changes to the keystone token flush interval. Backport where needed.
Relevant section: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/11/html-single/director_installation_and_usage/#sect-Tuning_the_Undercloud
See also the KeystoneCronToken values: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/11/html-single/overcloud_parameters/#identity_keystone_parameters
I think a more comprehensive section is needed for this topic.
