[RFE] Support for UEFI deployment in DevStack / Gate tests for UEFI deployments

[Lucas Alvares Gomes]

This RFE is about adding support for configuring nodes to be deployed in UEFI mode in DevStack. Later, we would also like to have tests for UEFI deployments in the Ironic gate (probably by switching an exiting job to use UEFI instead of creating a new job).

The distros supported in this first iteration are: Ubuntu 16.04 and Fedora 24.

Currently problems:

* The last released version of the Cirros images (released in May 2015) does not support UEFI. But fortunately the work to support UEFI in cirros is already merged and present on the daily built images [0] starting from 21/07/2016 [1].

* Ubuntu Xenial also hits: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1483071 but can be worked around.

* Hit: https://bugs.linaro.org/show_bug.cgi?id=858 a few times

* Apparently boot from local (whole disk image) requires the disk controller to be IDE, virtio does not work. https://lime-technology.com/forum/index.php?topic=39493.0

    DevStack: Use Jinja2 for templating when creating new VMs

    This patch is changing the configure-vm.py script to use Jinja2
    templating when creating new VMs instead of string interpolation.

    Jinja templating allows more complex templating such as conditionals
    which will greatly simplify the code for creating Legacy BIOS or UEFI
    supported VMs.

    DevStack: Support for creating UEFI VMs

    This patch is enhancing the create-node.sh script to allow creating UEFI
    capable VMs. Two new options were added:

    * -L (UEFI Loader): For specifying the absolute path to the UEFI LOADER
    * -N (UEFI NVRAM): For specifying the absolute path to the non-volatile
                       memory to store the UEFI variables, if needed.

Reason: agree with Jay - I started this as an attempt to improve grenade test time, but the current state of newton gates does not allow to test it anyway...

    DevStack: Configure nodes/environment to boot in UEFI mode

    This patch is adding support for DevStack to configure nodes and
    environment (Ubuntu and Fedora) to deploy nodes in UEFI mode.

    A new configuration called IRONIC_BOOT_MODE was added to DevStack and
    supports two values: "bios" and "uefi". Defaults to "bios".
