Removes the it `fails to execute confListDel given no 'plugins' key"` test.
This test no longer fails after libcni version 1.2.3.
It probably shouldn't failduring a DEL action as it is, we want the least error prone path.
The GC test now uses both cni.dev attachment formats.
Uses both attachment formats as per https://github.com/containernetworking/cni/issues/1101 for GC's cni.dev/valid-attachments & cni.dev/attachments
* config, daemon: shim socket path is not needed
The shim socket dir attribute is only required for the shim (cni
configuration). Thus, it can be removed from the daemon configuration.

* docs, thick plugin: align docs with new configuration reference
PR #1053 - [0] - changed the thick plugin configuration to happen
exclusively via the user provided config map. This PR aligns the multus
documentation with the existing code.

* Draft for refine options
* config: remove command line args; use configMap/JSON config
The `socketDir` configuration was split in two, since the multus daemon,
and multus shim have the socket in different paths. This allows the user
to customize these paths.

This change fix license boilerplate and its copyright.
The updated year in copyright is based on the file creation date.
If older than 2021, added copyright is transfered to multus
authors from Intel corporation as the multus code was officially
transfered to Kubernetes Networking Plumbing Working Group on
March 11, 2021.
This changes introduce delegate API function in multus-daemon.
This API will be consumed from other programs for hot-plug
interface into running pod. This change also cleanups server
code to split into client code and server code to easy to import
from other golang code.
Multus is refactored as a thick plugin, featuring 2 main components:
- a server listening to a unix domain socket, running in a pod
- a shim, a binary on the host that will send JSON requests built from
its environment / stdin values to the aforementioned server.
The pod where the multus daemon is running must share the host's PID
namespace.

thick, config: validate the cni config passed by the runtime
Without this patch, we're blindly trusting anything sent by the server.
This way, we assure the requests arriving at the multus controller are
valid before hand.

To keep consistency between actual network and CNI result in cache,
update libcni cache when multus add/del default routes by
`default-route` network selection.
If the runtime passes a pod UID via K8S_POD_UID (which both CRIO and
containerd do as of mid-2021) then fail if the pod we get from the
Kube API has a different UID. This would indicate that the pod was
deleted and recreated while Multus was attempting to set up
networking for the old pod instance's sandbox, and it's pointless
to continue setting up a sandbox for a dead pod instance.
Also pass the pod UID through to plugins so they can perform
additional checking and validation on the pods they get from the
Kube API.

Today, Multus will always log via STDERR, and these logs will then
logged by the Kubelet. If we also choose to have Multus log to a file by
setting the LogFile option in the CNI configuration, the same logs will
be logged twice.
This commit provide the option to disable logging to STDERR.
