Updates the dhcp-all-interfaces element so that
we add new DHCP interfaces using a udev rule
instead of a systemd service.
The previous approach (using the systemd service)
was proving to be problematic when used with
the new Fedora constistent network naming
convention rules (em1, em2, etc.). We aren't using
these device names as a default yet... but we will
need to soon and when we do udev rules seem to be the
best way to avoid racy behaviour when calling
dhcp-all-interfaces.sh from the systemd service.

Refactors dhcp-all-interfaces.sh so that if an optional
INTERFACE argument (the first argument) is passed to the script
it only inspects that single interface. If no argument is
passed then the previous default behaviour use used which
causes all interfaces to be inspected.
Also sets PATH so that the commands within the script
can all be found if it isn't set properly (/sbin/ip, /bin/cat, etc.)
This is a move towards using udev rules to add these types
of interfaces automatically.

Don't assume environment.d is always under /tmp/in_target.d. This makes
dib-run-parts more flexible, and less specific to diskimage-builder. For
instance, dib-run-parts is already used by os-refresh-config, but
/tmp/in_target.d/environment.d is never going to exist when it's called
by os-refresh-config.
This is useful b/c elements can now install os-refresh-config scripts
under /opt/stack/os-config-refresh/environment.d to influence how
further scripts are run. Specifically, the OpenSuse packages prepend the
OpenStack user accounts with "openstack-". Instead of checking for which
users exists with an if/else in all the os-refresh-config scripts that
need to do user related things, we can just update the scripts to use
$NOVA_USER, etc. The OpenSuse element can then install a file under
/opt/stack/os-config-refresh/environment.d to set NOVA_USER to
openstack-nova. We could have files that declare defaults as well within
each specific element, or just set a default variable at the top of each
os-refresh-config script.

Updates dhcp-all-interfaces so that we avoid using
ifquery on Fedora to determine if an interface exists.
Adds a new config_exists function which simply looks for
the ifcfg config file on distro's that use netscripts.

With https://review.openstack.org/#/c/70721 installing
the dhcp-agent subpackage was introduced, which is needed
for openSUSE. It seems on Fedora this is part of the main
package, so we need to map it back to that one.

Just adding an element shouldn't make a disk image build crash, even if
we're not using the element for its intended purpose.

Adds the ability to set $DIB_LOCAL_IMAGE to use as the base cloud image
for a Fedora image build. There are many repetitve tasks that are done
every image build. With this change you can build an image with the
fedora and vm element and then reuse the resulting image as input to
future image builds. This greatly reduces future image build times.
For instance 99-up-to-date is already taking almost 2 minutes (even with
rpm downloads already cached) for Fedora 20, and is only going to keep
taking longer. By having a local up to date Fedora cloud image, this
time can be saved on each image build.
There is one minor change to support this in that /tmp/grub needs to get
cleaned up at the end of image builds so that the image can be reused.
Plus, there is no reason for it to stick around anyway. (didn't think
this was worth a seperate commit).

Otherwise some dependend libraries might be missing in the ramdisk. E.g.
on SUSE bash is dynamically linked against libreadline.

/usr/bin/env is more portable (/bin/env does not exist on SUSE).
Also address minor nit on review about python 3.x compatibility.

Rename generate-interfaces-file.sh to dhcp-all-interfaces.sh
so that it is easier to find/remember in the $PATH on a deployed
image.
Also, on some distros the script actually generates many files
so the previous name was a bit confusing.

Updates the generate-interfaces-file.sh script in
the dhcp-all-interfaces element so that we only
add interfaces that have real MAC addresses.
The generate-interfaces-file.sh script is run early enough
in the boot process (before OVS is initialized) that this
isn't usually a problem unless you execute it manually by hand
after booting. Then you'll end up with network/DHCP
configs for all of your OVS bridges, etc. This
patch avoids configuring all of the virtual interfaces
which have generated MAC addresses.
