Support online volume expansion Summary: Online volume expansion is a 2 phase process: 1. The backing storage, in this case the raw file, needs to be resized. (i.e. `truncate -s`) 2. The node should be notified, so that it can both refresh its device capacity (i.e. `losetup -c`) and resize the filesystem (`resize2fs`) accordingly. Although in our case both steps could be performed on the node itself, for the sake of following the semantics of how volume expansion works, we perform step 1 from the controller, and step 2 from the node. Also, the `external-resizer` component is added which watches for PVC size updates, and notifies the CSI controller about it. Test Plan: Setup: - Deploy - Create a rawfile-backed pvc, and attach a Deployment to it - Keep an eye on `rawfile` pod logs in `kube-system` namespace to see if any errors pop out during all scenarios Scenario 1: - Increase the size of the pvc - Exec into the pod and verify that the volume is resized indeed (using `df`) Scenario 2: - Decrease deployment's replica to 0 - Increase the size of the pvc. Wait for a couple of minutes. - Increase deployment's replica to 1 - Exec into the pod and verify that the volume is resized indeed.
