f58f859303 Only configure DHCP for real interfaces
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.

ae28c99b5f Retry link check up to 10 times.
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...

7511faa2b1 Implement dhcp-all-interfaces for systemd.
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.

43b70ce224 /bin/bash all the things.
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.

d23ba2a8a8 Conditionally add dhcp-all-interfaces
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.

f96f705559 Remove \r chars from dhcp-all-interfaces
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.

28190d5954 Make dhcp-all-interfaces block all interfaces
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.

2129d78124 Fix ifquery call in dhcp-all-interfaces
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.

4a751ba162 Generate interfaces file before cloud-init runs
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.

2684cddd3d Fix typo in dhcp-all-interfaces.
It is meant to write to /etc/network/interfaces, not
/etc/network/interfaces].

a6b794fffc Add element to run DHCP on all network interfaces.
Ensures that all network interfaces are present in
/etc/network/interfaces. Any interface not already defined there
will be added and configured for DHCP.
