Bug Description

Currently the iso element sets its grub root by searching for vmlinuz. When the deployed image on the disk contains /vmlinuz file, grub chooses that as the root partition which causes grub to fail to read the configuration file.

(hd0) -> disk on the baremetal node
   (hd0, 1) -> partition on the baremetal node

(cd0) -> virtual media attached on baremetal node.

When (hd0,1) has a file named /vmlinuz, currently created ISO image in grub chooses (hd0,1) as the root partition and fails to boot.

    iso element to use 'search --label' for grub

    Current iso element uses 'search --file' to find the
    grub root. This is a wrong approach as it may find
    some other partition containing /vmlinuz. Instead modify
    it to search for grub root by the label of ISO image.
