Use labels for virtual media dev in Ironic ramdisk
This commit changes Ironic deploy ramdisk to find out the virtual media device by using labels instead of looking at the model of block device. This helps in finding out the device irrespective of the hardware. Corresponding Ironic change is If5b78d9af7048f2631d050ee5ce01ab7a67e2354. Closes-Bug: #1429340 Change-Id: I5e8a706989bad13051eb47db0b1e762e6c672318
