[cinder][kolla][OSA][release] Xena cycle-trailing release deadline

Hello teams with deliverables following the cycle-trailing release model!

This is just a reminder to wrap up your trailing deliverables for Xena. A few cycles ago the deadline for cycle-trailing projects was extended to give more time. The deadline for Xena is *16 December, 2021* [1].

If things are ready sooner than that though, all the better for our downstream consumers.

For reference, the following cycle-trailing deliverables will need final releases at some point until the above deadline:

Thanks!
