Stefan Junker 680d1f6ec2 *: appc/cni -> containernetworking/cni
The project has been moved so internally we simply rename everything.
Consumers are recommended to update their vendored version of cni.

# dhcp plugin
## Overview
With dhcp plugin the containers can get an IP allocated by a DHCP server already running on your network.
This can be especially useful with plugin types such as [macvlan](https://github.com/containernetworking/cni/blob/master/Documentation/macvlan.md).
Because a DHCP lease must be periodically renewed for the duration of container lifetime, a separate daemon is required to be running.
The same plugin binary can also be run in the daemon mode.
## Operation
To use the dhcp IPAM plugin, first launch the dhcp daemon:
```
# Make sure the unix socket has been removed
$ rm -f /run/cni/dhcp.sock
$ ./dhcp daemon
```
Alternatively, you can use systemd socket activation protocol.
Be sure that the .socket file uses /run/cni/dhcp.sock as the socket path.
With the daemon running, containers using the dhcp plugin can be launched.
## Example configuration
```
{
"ipam": {
"type": "dhcp",
}
}
## Network configuration reference
* `type` (string, required): "dhcp"
