User-disks are supported by QEMU and Firecracker providers. Can be defined by using the following parameters: ``` --user-disk /mount/path:1GB ``` Can get more than 1 user disk. Same set of user disks will be created for all master and worker nodes. Additionally enable user-disks in qemu e2e test. Signed-off-by: Artem Chernyshev <artem.0xD2@gmail.com>
