Ironic: Add deploy kernel and deploy ramdisk to driver_info

Pass deploy kernel and deploy ramdisk as parameters to the driver
to enable Ironic to support different deploy provisioning
methods using the same flavor. This patch is part of the
https://blueprints.launchpad.net/ironic/+spec/add-node-instance-info
work which is separating the instance-level data from the driver-leval
data in the Node's resource of Ironic, once it's finished another patch
will be submitted to DevStack to remove the part of the code which is
adding the deploy kernel and deploy ramdisk parameters to the flavor,
for now a TODO was left inline as a reminder.

[Fedora] Devstack fails to install in firewalld less system

The official F20 cloud image does not contains the firewalld,
there is nothing to restart, and it fails the installation.

The previous workaround change, assumed all is_fedoras has
a restartable firewalld without ensuring is it installed at all.

RHEL6 even does not have a firewalld.

Support multiple Cinder backend types

This is the first step in supporting multiple Cinder backend types at
once.  It initially converts the existing hard-coded multi-lvm support
to a new cinder_backends driver form.  Eventually the cinder_plugins
will be converted to this form so they can be enabled more than just
one at a time.

The default configuration should be identical to the previous defaults,
including for both True and False values of CINDER_MULTI_LVM_BACKEND.

The existing cinder_plugins are expected to be removed when this is
complete. They should continue to work until they have been converted.
