node-validate fails for boot and deploy on agent_* drivers

[Thiago Paiva Brito]

With fresh devstack, although having 'deploy_kernel' and 'deploy_ramdisk' the node's driver_info, Ironic fails validating the node on boot and deploy interfaces due to lack of 'kernel', 'ramdisk' and 'image_source' on instance_info. This was tested on agent_pxe_oneview and agent_ssh drivers.

This is a correct behavior. These fields are either populated by nova or manually before installation. Note that these 3 fields are for instance parameters, setting 'deploy_kernel' and 'deploy_ramdisk' does not affect them.
