Introduce the following options :-
1. XEN_LOAD - This specifies command to load xen hypervisor binary and device
tree.
2. DOM0_LOAD - This specifies command to load Dom0 binaries.
3. DOMU_LOAD[] - This specifies command to load DomU binaries.
There can be situations where Xen, Dom0 and DomU binaries are stored in
different partitions. Thus, imagebuilder should provide a way the binaries
using different commands.
If any of the above options are not specified, LOAD_CMD is used by default.

This patch should be applied first.
Changes from :-
v1 - 1. Make LOAD_CMD optional when XEN is set
2. find_root_dev() should be invoked with either "$DOM0_CMD" or "$LOAD_CMD"
depending on if it is invoked from xen_config() or linux_config().
3. User needs to set either LOAD_CMD or XEN_LOAD. If neither is set, throw
an error. This is true for DOM0_LOAD and DOMU_LOAD[].

with a small caveat: the exits should be exit 1 because they are due to
errors. I made the change on commit.
