This may make it easier for users to find info on logging parameters since there isn't a dedicated docs page for it.

* types: fix usage of strings.Split() for parsing CNI_ARGS
strings.Split() returns a slice, in this case with two elements of
the key and value. As such we shouldn't range over the slice when
the code is expecting a 2-element slice of key/value.
Otherwise we get errors for valid CNI_ARGS like:
2022-04-22T11:53:54Z [error] CreateCNIRuntimeConf: CNI_ARGS K8S_POD_NAMESPACE=openshift-etcd K8S_POD_NAMESPACE 17 is not recognized as CNI arg, skipped
2022-04-22T11:53:54Z [error] CreateCNIRuntimeConf: CNI_ARGS K8S_POD_NAMESPACE=openshift-etcd openshift-etcd 14 is not recognized as CNI arg, skipped

* types/conf: fix handling of CNI_ARGS additions to rt.Args
We want to set the CNI_ARGS value in rt.Args if the existing value
is empty, not if the key doesn't exist yet. Since the rt.Args array
is pre-created with the K8S args keys, empty values of those keys
couldn't be overwritten with the previous scheme that just checked
if the key existed.
If the CNI_ARGS key wasn't found in rt.Args then add it; previously
a typo ("isExists != false") prevented that with inverted logic.

* multus: entrypoint: disallow incompatible cni versions
When top level CNI version is 0.4.0 or more, nested CNI version
can't be less than 0.4.0 since these are incompatible. This
closes issue #737.

add the same logic in go for the thick plugin.

This change make binary file and directory name consistent.
In addition, change the package name cni to server because cni
is a bit umbiguous for cni plugin's repository.
setenv refers environment variables, which is unique in process,
not unique to go routine. Hence it may causes some issue in multi
threaded case, hence it is replaced with libcni's runtimeConfig
value set to set these variables at libcni side, after process
fork.
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.
