[BUG] waagent doesn't mount temporary storage on Gen2 VMs

[msftphleiten]

temporary storage is not mounted and therefor swap space doesn't get active with error:

2019/09/17 07:43:28.253251 INFO Daemon Activate resource disk
2019/09/17 07:43:28.255774 ERROR Daemon Failed to mount resource disk [ResourceDiskError] unable to detect disk topology
2019/09/17 07:43:28.257645 ERROR Daemon Event: name=WALinuxAgent, op=ActivateResourceDisk, message=[ResourceDiskError] unable to detect disk topology, duration=0

disks are not SCSI and not IDE anymore.

def mount_resource_disk(self, mount_point):

  | device = self.osutil.device_for_ide_port(1)
  | if device is None:
  | raise ResourceDiskError("unable to detect disk topology")

it only applies to Gen2 VMs (Mv2) as this changes the way disks are handled.
