* build: provide a docker img for daemon based deployments
We will have 2 different images (only on amd64 archs):
- legacy entrypoint script based
- daemonized process
The `image-build` docker action is updated, to build these 2 images.
There will be 2 different deployment specs, along with e2e test
lanes, one for each of the aforementioned alternatives.

* build: delegate CNI config watch loop via golang
For the thick-plugin alternative, provide the watch loop for
configuration regeneration via a golang binary.
Over time, this binary is expected to run the control loop to watch
out for pod updates.
To enable current multus users to chose when they upgrade to this new
deployment setup, these changes are provided in separate multus images,
having a different yaml spec files. Both of these alternatives are
tested e2e, since a new lane is introduced.
The following libraries are introduced, along with the motivation for
adding them:
- dproxy: allows traversing the default network configuration arbitrarily,
similar to what an X path / JSON path tool provides.
Repo is available at [0].
- fsnotify: watch for changes in the default CNI configuration file.
Repo is available at [1].
The config map providing the default network CNI configuration is not
copied over, since originally, the user was not required to install a
default network CNI plugin first, but, nowadays, this is a required
step of multus.
As such, it is no longer required to provide a default CNI
configuration.

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.

This PR updates the GitHub Actions workflows to build multus
container images for the IBM Z architecture (s390x), and also
adds daemonsets for s390x nodes.
entrypoint.sh uses python3 when it is available, since centos images
are not available for s390x, and python2 is not installed by default
on debian-based images.

entrypoint script fails with error when try reading capabilities in

Signed-off-by: Mamduh Alassi <mamduhala@mellanox.com>
Using Python, we analyze the content of the master plugin configuration,
and we integrate any capabilities from the underlying chained plugins
declaration. We only pull enabled capabilties from the underlying
(chained) plugin definitions.

This change introduces multus-daemonset-crio again to support crio.
The change also introduce '--override-network-name' to use previous
master name in CNI json for multus CNI json.
This change introduces two fix about CNIVersion. One is to add CNIVersion into
delegated CNI conflist in case of DEL if CNIVersion is missing. ParseVersion() in libcni
checks cniVersion as mandatory field and sometimes user/daemonset miss it.
The latest flannel daemonset yaml (of flannel github) does not have CNIVersion, for example.
This change adds CNIVersion from multus config if cniVersion is missing (empty) in delegated
CNI config.
In addition, this fix also adds '--cni-version' in entrypoint.sh to add cniVersion in multus
config in case of '--multus-conf-file=auto'.
When `--multus-conf-file=auto` is used, 00-multus.conf will be
automatically generated from the CNI configuration file of the master
plugin (the first file in lexicographical order in cni-conf-dir).
