That is the ovs-vsctl default but Ansible module is failing in
reconfigure step - and secure breaks external connectivity in
OVN.
From OVS docs:
fail_mode: optional string, either secure or standalone
When a controller is configured, it is, ordinarily, responsible
for setting up all flows on the switch. Thus, if the connection
to the controller fails, no new network connections can be set
up. If the connection to the controller stays down long enough,
no packets can pass through the switch at all. This setting de‐
termines the switch’s response to such a situation. It may be
set to one of the following:
standalone
If no message is received from the controller for three
times the inactivity probe interval (see inactiv‐
ity_probe), then Open vSwitch will take over responsibil‐
ity for setting up flows. In this mode, Open vSwitch
causes the bridge to act like an ordinary MAC-learning
switch. Open vSwitch will continue to retry connecting to
the controller in the background and, when the connection
succeeds, it will discontinue its standalone behavior.
secure
Open vSwitch will not set up flows on its own when the
controller connection fails or when no controllers are
defined. The bridge will continue to retry connecting to
any defined controllers forever.
The default is standalone if the value is unset, but future ver‐
sions of Open vSwitch may change the default.

Kolla Ansible
The Kolla Ansible is a deliverable project separated from Kolla project.
Kolla Ansible deploys OpenStack services and infrastructure components in Docker containers.
Kolla's mission statement is:
To provide production-ready containers and deployment tools for operating
OpenStack clouds.Kolla is highly opinionated out of the box, but allows for complete customization. This permits operators with little experience to deploy OpenStack quickly and as experience grows modify the OpenStack configuration to suit the operator's exact requirements.
Getting Started
Learn about Kolla Ansible by reading the documentation online Kolla Ansible.
Get started by reading the Developer Quickstart.
