adds support for multiple iscsi disks with the syntax:
root=<normal block path or UUID or LABEL> \
netroot=iscsi:... netroot=iscsi:... netroot=iscsi:...
which is suboptimal, because you can't specify it in the dhcp protocol.
A better syntax would be a single netroot (also for FCoE disk) something like:
netroot=netdisks:iscsi:...[separator]iscsi:...[separator]fcoe:...
What do you think? Any better ideas?

be warned that DHCP option format is generally
code: 1 byte
lenght: 1 byte
data: lenght bytes
which would limit the lenght of the netroot string to 255 charachters
anyway.

255 chars can be sufficient for up to 4 disks

I think that will be a pain for the cmdline generating code in anaconda,
one argument per disk please. Note having this as netroot syntax and
a separate iscsi_disk= for the one argument per disk case would be fine.

We could support both.. iscsi_disk= and the combined netroot=
