[nova] destroy_secrets being added to nova.virt.driver.ComputeDriver.{cleanup, destroy}

Hello all, I'm looking to introduce and likely backport an optional kwarg to the signature of the cleanup and destroy virt driver methods below: virt: Add destroy_secrets kwarg to destroy and cleanup https://review.opendev.org/c/openstack/nova/+/794252 While this is optional for any callers any out of tree driver implementing either method will need to add this kwarg. This is part of the following bugfix series where I am attempting to avoid secrets from being destroyed during a hard reboot within the libvirt driver: https://review.opendev.org/q/topic:bug/1905701+status:open+branch:master Hopefully this is trivial but if there are any concerns or issues with this then please let me know! Cheers, Lee
