"""Prepares the boot of instance.
This method prepares the boot of the instance after reading
relevant information from the node's instance_info.
It does the following depending on boot_option for deploy:
- If the boot_option requested for this deploy is 'local' or image is
a whole disk image, then it sets the node to boot from disk.
- Otherwise it finds/creates the boot ISO, sets the node boot option
to UEFIHTTP and sets the URL as the boot ISO to boot the instance
image.
:param task: a task from TaskManager.
:returns: None
:raises: IloOperationError, if some operation on iLO failed.
:raises: InstanceDeployFailure, if its try to boot iSCSI volume in
'BIOS' boot mode.
