contrib: cni: provide example CNI configurations

Browse source 
This also updates the readme to no longer contain CNI configuration
information (which had incorrect steps), and rather just points to the
example configs.

### Setup CNI networking
Follow the steps below in order to setup networking in your pods using the CNI
bridge plugin. Nothing else is required after this since `CRI-O` automatically
setup networking if it finds any CNI plugin.
```sh
$ go get -d github.com/containernetworking/cni
$ cd $GOPATH/src/github.com/containernetworking/cni
$ sudo mkdir -p /etc/cni/net.d
$ sudo sh -c 'cat >/etc/cni/net.d/10-mynet.conf <<-EOF
{
"cniVersion": "0.2.0",
"name": "mynet",
"type": "bridge",
"bridge": "cni0",
"isGateway": true,
"ipMasq": true,
"ipam": {
"type": "host-local",
"subnet": "10.88.0.0/16",
"routes": [
{ "dst": "0.0.0.0/0" }
]
}
}
EOF'
$ sudo sh -c 'cat >/etc/cni/net.d/99-loopback.conf <<-EOF
{
"cniVersion": "0.2.0",
"type": "loopback"
}
EOF'
$ ./build
$ sudo mkdir -p /opt/cni/bin
$ sudo cp bin/* /opt/cni/bin/
```
A proper description of setting up CNI networking is given in the
[`contrib/cni` README](contrib/cni/README.md). But the gist is that you need to
have some basic network configurations enabled and CNI plugins installed on
your system.
### Running with kubernetes
You can run the local version of kubernetes using `local-up-cluster.sh`. After starting `ocid` daemon:

## `contrib/cni` ##
There are a wide variety of different [CNI][cni] network configurations. This
directory just contains some example configurations that can be used as the
basis for your own configurations (distibutions should package these files in
example directories).
To use these configurations, place them in `/etc/cni/net.d` (or the directory
specified by `ocid.network.network_dir` in your `ocid.conf`).
In addition, you need to install the [CNI plugins][cni] necessary into
`/opt/cni/bin` (or the directory specified by `ocid.network.plugin_dir`). The
two plugins necessary for the example CNI configurations are `loopback` and
`bridge`.
