Rajat Dhasmana a7edc87b0e Cinder: Add support to extend attached volumes ... While creating an image, if we want to extend the volume (to accomodate the image), we need to first detach the volume, perform the extend and attach it again. This is inefficient for backends that support extending attached volumes since we are performing 3 cinder operations (the attachment call includes 3 API calls which sum to a total of 5 API calls for 3 operations) instead of directly extending it which requires only 1 API call to cinder. The support for extending attached volumes was added in cinder microversion 3.42. This patch adds a new boolean config option ``cinder_do_extend_attached`` which allows operators to specify if the cinder backend they are using supports extending attached (in-use) volumes. By default this will be ``false``. Based on the parameter, we will perform the extend operation, online (if cinder_do_extend_attached is true) and offline otherwise.
