Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/expose-ramdisk-kernel-and-command-line-via-rest-and-cli.

Description:

In an effort to streamline the image creation process using OpenStack the following observations have been made: nova-compute RPC API provides that ability to specify ramdisk_id and kernel_id when creating an instance [1].  However, the REST API does not expose this functionality and the kernel_id and ramdisk_id are inherited from the image being used to launch the instance.  Another limitation is the inability to pass in the kernal command line.  

This blueprint proposes two changes:

   1) Exposing ability to pass in kernel_id and ramdisk_id from REST API and CLI.   
   2) Adding ability to pass in kernal command line from REST API and CLI

Making the kernel and ramdisk launch-time configurable more closely matches the existing EC2 behavior.
