TripleO deployment for Octavia getting failed because there is no valid Nova keypair
Considering the removal of Nova from undercloud/director node, there is no one who can generate a keypair, and the current Octavia deployment still thinks that it should get a keypair from Nova to work.
Below is the error message which we getting during deployment:
~~~

The highlighted section from the URL is getting called out for generating the keypair, https://opendev.org/openstack/tripleo-heat-templates/src/branch/master/deployment/octavia/octavia-deployment-config.j2.yaml#L207-L212

There are a couple of workarounds like manually providing a public key or comment-out the keypair generation part itself.
Looking for a solution where we can seamlessly deploy Octavia
Additional details:
1. Provider driver - Amphora
2. Facing problem for standalone/non-standalone deployments
So the problem is that we don't have Nova on the Director node in Tripleo. So we fail here:
https:/
When we try to reach out to the non existent API endpoint. Then we use that param here:
https:/
So this whole mechanism needs to be removed and replaced with something. I guess we would ideally do it with Ansible and generate a new key, then use that key during the deployment?
