- Merge dhclient-start and dhclient-stop into a single hook.
- Wait for a lease before returning from the hook.
- Generate a logfile when LXC log level is either DEBUG or TRACE.
- Rely on namespace file descriptors for the stop hook.
- Use settings from /<sysconf>/lxc/dhclient.conf if available.
- Attempt to cleanup if dhclient fails to shutdown properly.

This hook requires the nvidia-container-cli tool provided by libnvidia-container:
https://github.com/nvidia/libnvidia-container
For containers that do not have CUDA_VERSION or NVIDIA_VISIBLE_DEVICES
set in the environment, the hook will be a no-op.
To enable in the configuration file:
lxc.hook.mount = /usr/local/share/lxc/hooks/nvidia

Add new hooks leveraging dhclient from the host to automatically
configure the container interfaces. This is especially useful for
application containers which rely on an IPAM driver for network
configuration (e.g. Docker).

Also fix the comment in lxc-cirros template (which I overlooked last time).

This makes the ubuntu and ubuntu-cloud templates automatically aware of apt
proxy settings when the LXC host has "squid-deb-proxy-client" installed. This
makes installations *much* faster when a suitable squid-deb-proxy is
found on the network (or installed on the host).

This hook script updates the hostname in various files under /etc in the
cloned container. In order to do so, the old container name is passed in
the LXC_SRC_NAME environment variable.

We've been shipping those two hooks for a while in Ubuntu.
Yesterday I reworked them to use the new environment variables and
avoid hardcoding any path that we have available as a variable.
I tested both to work on Ubuntu 13.04 but they should work just as well
on any distro shipping with the cgroup hierarchy in /sys/fs/cgroup and
with ecryptfs available.
Those are intended as example and distros are free to drop them, they
should however be working without any change required, at least on Ubuntu.
