This change sets the mac address if specified during the creation of the
macvlan interface. This is superior to setting it via the tuning plugin
because this ensures the mac address is set before an IP is set,
allowing a container to get a reserved IP address from DHCP.

This PR add the option to configure an empty ipam for the macvlan cni plugin.
When using the macvlan cni plugin with an empty ipam the requeted pod will get the macvlan interface but without any ip address.
One of the use cases for this feature is for projects that runs a dhcp server inside the pod like KubeVirt.
In KubeVirt we need to let the vm running inside the pod to make the dhcp request so it will be able to make a release an renew request when needed.
Now that libcni has the ability to print a version message, plumb it
through correctly.
While we're at it,
- fix import paths
- run gofmt
- add some more comments to sample
- add container runtime swappability for release
host-local and static ipam plugins
tuning, bandwidth and portmap meta plugins
Utility functions created for common PrevResult checking
Fix windows build
Recent CNI specification changes require the container ID on ADD/DEL,
which the testcases were not providing. Fix that up so things work
when this repo gets CNI revendored.
Namespace creation had an unergonomic interface and isn't used, except
for testing code. Remove it; downstream users should really be creating
their own namespaces
Updates the spec and plugins to return an array of interfaces and IP details
to the runtime including:
- interface names and MAC addresses configured by the plugin
- whether the interfaces are sandboxed (container/VM) or host (bridge, veth, etc)
- multiple IP addresses configured by IPAM and which interface they
have been assigned to
Returning interface details is useful for runtimes, as well as allowing
more flexible chaining of CNI plugins themselves. For example, some
meta plugins may need to know the host-side interface to be able to
apply firewall or traffic shaping rules to the container.
* bridge: Test the following interface's hardware address for the CNI specific
prefix:
- bridge with IP address
- container veth
* plugins/macvlan test: ensure hardware addr
This will give deterministic MAC addresses for all interfaces CNI
creates and manages the IP for:
* bridge: container veth and host bridge
* macvlan: container veth
* ptp: container veth and host veth
Add a namespace object interface for somewhat cleaner code when
creating and switching between network namespaces. All created
namespaces are now mounted in /var/run/netns to ensure they
have persistent inodes and paths that can be passed around
between plugin components without relying on the current namespace
being correct.
Also remove the thread-locking arguments from the ns package
per https://github.com/appc/cni/issues/183 by doing all the namespace
changes in a separate goroutine that locks/unlocks itself, instead of
the caller having to track OS thread locking.
