Updates the dhcp-all-interfaces element so that the link
check tries up to 10 times.
On some of my machines 3 times (seconds) doesn't appear to
be quite long enough...

Includes:
* Enhancements to the generate-interfaces-file.sh script
so that it generates ifcfg network-scripts for
distros like Fedora/RHEL.
* Includes a new dhcp-all-interfaces.service systemd
script which ensures network interfaces get generated
before the network service starts on Fedora.
* Add a new disable_interface function to
generate-interfaces-file.sh which (on Fedora)
will delete the ifcfg config for an interface which
isn't plugged in.
This is important because ifcfg-eth0 exists by default
and we want to remove it if the NIC isn't connected.
Previous behaviour on Ubuntu is unchanged and the
generate-interfaces-file.sh just logs it as skipped.
* General doc updates...
I tested this on a multi-nic machine w/ Fedora where the first NIC
exists but was not connected.

Since we are using bash syntax in some of the element fragments,
we should make sure we use bash for all of them, so that things don't
break on systems where /bin/sh != /bin/bash.

If the /etc/init drectory gets created on Fedora, it causes
os-svc-daemon to add upstart init scripts instead of systemd.
As a result none of the openstack services can start.

For some reason we are adding CR's to/etc/network/interfaces, but it
does not require them. They are a bit annoying to see in an editor and
serve no known purpose there.

Previously dhcp-all-interfaces was only blocking the first network
interface to come up. We add an instance stanza to make it run one
instance of generate-interfaces-file per interface. We then use flock to
serialize runs of generate-interfaces-file.

Ifquery does not print anything for interfaces which only have a single
iface line. It does, however, return non-zero if the interface is not
configured at all, so we can use that to indicate whether or not there
is a configuration.

Cloud-init needs to query the metadata server after the network
interfaces are configured. The upstart job "cloud-init-nonet" is
specifically in place to provide a hook to block cloud-init from
running while we rearrange network interface configurations.

Ensures that all network interfaces are present in
/etc/network/interfaces. Any interface not already defined there
will be added and configured for DHCP.
