Bug Description

The current iPXE support depends on configuration files to be cached in the disk. This creates a dependency between a given ironic-conductor a given node (even without a conductor lock on a node) because that ironic-conductor is the only one able to boot that node. This also makes take-over more complicated because the new ironic-conductor will need to regenerate the iPXE configuration files for the new nodes it's now managing and update the DHCP server accordingly.

This RFE proposes to add support for dynamically generating iPXE configuration files when booting a node.

    Convert iPXE boot script to Jinja template

    This will not affect those using custom out-of-tree boot scripts,
    as such files will be rendered as-is.

    This patch also moves template rendering to a common place and sets
    create_pxe_config to use it.
