[Bug 2077348] Please test proposed package

[Timo Aaltonen]

Hello Evgeniy, or anyone else affected,

Accepted octavia into jammy-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/octavia/1:10.1.1-0ubuntu1.2 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  [Impact]

  Loadbalacer stuck in status PENDING_DELETE if TLS cert unavailable

  [Test Case]

  Pls refer to [Test steps] section below.

  [Regression Potential]

  The fix is already in the upstream main, stable/2024.1, stable/2023.2,
  stable/2023.1 branches, so it is a clean backport and might be helpful
  for deployments using octavia.

  I also test this fix, it works well -

  Original Bug Description Below
  ===========

  Loadbalacer stuck in status PENDING_DELETE if TLS cert unavailable

  1. Create load balancer with TERMINATED_HTTPS listener
  2. Disable your TLS storage, or delete cert from storage
  3. Try to delete loadbalancer with cascade flag

  Error on logs:

  ```
  Unable to retrieve certificate(s) due to Could not retrieve certificate: <some id>
  Exception during message handling
  ```

  ```

  ```

  [Test steps]

  1. Create load balancer with TERMINATED_HTTPS listener, eg:

  secret1_id=$(openstack secret store --name='lb_tls_secret_1' -t 'application/octet-stream' -e 'base64' --payload="$(base64 < www.server1.com.p12)" -f value -c "Secret href")
  octavia_user_id=$(openstack user show octavia --domain service_domain -f value -c id); echo $octavia_user_id;
  openstack acl user add -u $octavia_user_id $secret1_id
  subnetid=$(openstack subnet show private_subnet -f value -c id); echo $subnetid
  lb_id=$(openstack loadbalancer create --name lb1 --vip-subnet-id $subnetid -f value -c id); echo $lb_id
  listener_id=$(openstack loadbalancer listener create $lb_id --name https_listener --protocol-port 80 --protocol TERMINATED_HTTPS --default-tls-container=$secret1_id --sni-container-refs $secret1_id $secret2_id -f value -c id); echo $listener_id

  2. Disable your TLS storage, or delete cert from storage, eg:

  openstack secret delete $secret1_id

  3. Try to delete loadbalancer with cascade flag

  openstack loadbalancer delete lb1 --cascade
