Vinícius Ferrão 52e468884e fix(grub2): keep the whole kernel command line past a grub2 separator
grub2 reads its configuration as a script, so an unquoted command separator
ends the linux command and everything after it is lost. The Ubuntu
installer seed is written as ds=nocloud-net;s=<url>, so the node booted
without the seed URL and without the arguments that followed it, including
BOOTIF. The installer then found no autoinstall configuration and waited
for someone to answer its questions. A separator that is neither escaped
nor inside a quoted span is now escaped where it stands, which grub2
removes before it hands the line to the kernel. A value the caller escaped
or quoted keeps exactly the form the caller gave it.

=head3 getNodesetStates
returns the nodeset state for the given nodes. The possible nodeset
states are: netboot, install, boot and discover.
Arguments:
nodes --- a pointer to an array of nodes
states -- a pointer to a hash table. This hash will be filled by this
function.The key is the nodeset status and the value is a pointer
to an array of nodes.
Returns:
(return code, error message)
