[nova] context being introduced to nova.virt.driver.ComputeDriver.extend_volume

Hello all, I'm looking to introduce the request context to the signature of extend_volume in the following change: virt: Pass request context to extend_volume https://review.opendev.org/#/c/706899/ Any out of tree drivers implementing extend_volume will also need to add the request context to their implementations once this lands. This is part of a wider bugfix series below: https://review.opendev.org/#/q/topic:bug/1861071 Also discussed on the ML in the following thread: http://lists.openstack.org/pipermail/openstack-discuss/2020-February/012551.... If there are any concerns or issues with this then please let me know! Cheers, -- Lee Yarwood A5D1 9385 88CB 7E5F BE64 6618 BCA6 6E33 F672 2D76
