This commit adds two initcontainers in a kustomize overlay to QAT
deployment. The overlay can be used to prepare QAT setup on a freshly
booted system.
Note: containerd/cri-o seem to have issues mounting sysfs rw in even
if the container is privileged. Therefore, we do a special /sys:/sys
bind mount for 'cat sriov_totalvs | tee sriov_numvfs' to work.

Some Ubuntu systems may run with Apparmor LSM policy enformements making
the default QAT daemonset to fail with (un)bind errors.
This commit adds a sample kustomize overlay to deploy the QAT daemonset with
Apparmor uconfined policy.

Move the framework, and the qat driver, to use `klog`
for logging and debug.
This has a some noticeable effects:
1) Our default log output gains a bunch of annotation:
From:
QAT device plugin started in 'dpdk' mode
To:
I0312 11:51:02.057728 6053 qat_plugin.go:64] QAT device plugin started in 'dpdk' mode
(there is now a command line option to drop those annotations if
necessary).
2) We gain a bunch of command line parameters from klog for controlling log
levels and output. We go from 5 arguments to 17:
---
Usage of ./cmd/qat_plugin/qat_plugin:
-add_dir_header
If true, adds the file directory to the header
-alsologtostderr
log to standard error as well as files
-debug
enable debug output
-dpdk-driver string
DPDK Device driver for configuring the QAT device (default "vfio-pci")
-kernel-vf-drivers string
Comma separated VF Device Driver of the QuickAssist Devices in the system. Devices supported: DH895xCC,C62x,C3xxx and D15xx (default "dh895xccvf,c6xxvf,c3xxxvf,d15xxvf")
-log_backtrace_at value
when logging hits line file:N, emit a stack trace
-log_dir string
If non-empty, write log files in this directory
-log_file string
If non-empty, use this log file
-log_file_max_size uint
Defines the maximum size a log file can grow to. Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
-logtostderr
log to standard error instead of files (default true)
-max-num-devices int
maximum number of QAT devices to be provided to the QuickAssist device plugin (default 32)
-mode string
plugin mode which can be either dpdk (default) or kernel (default "dpdk")
-skip_headers
If true, avoid header prefixes in the log messages
-skip_log_headers
If true, avoid headers when opening log files
-stderrthreshold value
logs at or above this threshold go to stderr (default 2)
-v value
number for the log level verbosity
-vmodule value
comma-separated list of pattern=N settings for file-filtered logging
---
3) Our `-debug` flag is now replaced by the `klog` `-v n` flag.
*NOTE:* This is potentially a minor breaking change. Applying
this debug overlay to any previous (pre-klog edit) images will
cause the container to fail to launch, as it will not recognise
the new `-v` arguments.
We also update the kustomize deployment to move from using
DEBUG env vars to adding a VERBOSITY var that controls both
the log verbosity and now the debug mode enabling.

Previously, /dev/vfio/xx devices were just arbitrary strings and the
plugin did not need the devices for anything. After adding the checks
for topology hints, we need to read the devices attached to those so
the device nodes must be bind mounted in the plugin container.
Moreover, be more verbose about any errors coming from the topology code.

In preparations to get some of the images to hub.docker.com/intel,
start using intel/ prefix.
Moreover, set the Makefile variables so that the images built
by make [images|demos] can easily be pushed to any registry/org
by 'docker push' (e.g., by Jenkins).

For easier deployments, fetch plugin command line arguments from ConfigMap.
When using ConfigMaps, qat_plugin.yaml needs no changes and can always
be used as is.
qat_plugin_default_configmap.yaml uses built-in defaults.
