dhcp-all-interfaces doesn't take effect early enough for cloud-init

[Robert Collins]

I fixed dhcp-all-interfaces to work :) then tried it.

The machine booted and came up on the right IP - yay!. But it didn't have ssh keys from cloud-init.

I rebooted it, and once it came up, it was good.

    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.

    Fixes bug #1233577

This fix didn't :(.

cloud-init-nonet didn't find an interface in a freshly built image on a machine with 4 interfaces, link on eth3; the machine is available for examination on 10.10.16.173 in the tripleo-cd cloud.

    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.

    Fixes bug #1233577
