Allow using TempURLs for deploy images
when iPXE is enabled, it is possible for the bootloader to download
the deploy kernel and ramdisk directly from Swift TempURL instead of
downloading them to conductor and serving from local HTTP server.
This patch adds the required logic and a new config option
`ipxe_use_swift` (default False), setting which to True enables
using Swift TempURLs for deploy ramdisk and kernel.
Note that local caching and serving for kernel and ramdisk of user image
is still performed for partition images that require non-local boot,
as moving those to use TempURLs will make it impossible for the user
to reboot the instance when TempURLs time out or image is deleted from
Glance/Swift.
