(default: "/run/containerd/containerd.sock") is duplicated when
printing kata-monitor usage:
[root@kubernetes ~]# kata-monitor --help
Usage of kata-monitor:
-listen-address string
The address to listen on for HTTP requests. (default ":8090")
-log-level string
Log level of logrus(trace/debug/info/warn/error/fatal/panic). (default "info")
-runtime-endpoint string
Endpoint of CRI container runtime service. (default: "/run/containerd/containerd.sock") (default "/run/containerd/containerd.sock")
the golang flag package takes care of adding the defaults when printing
usage. Remove the explicit print of the value so that it would not be
printed on screen twice.

The idea is to pass this README file to kata-doc-to-script.sh script and
then execute the result.
Added comments with a file name on top of each YAML snippet.
This helps in assigning a file name when we cat the YAML to a file.

`make kata-tarball` relies on `kata-deploy-binaries.sh -s` which
silently ignores errors, and you may end up with an incomplete
tarball without noticing it because `make`'s exit status is 0.
`kata-deploy-binaries.sh` does set the `errexit` option and all the
code in the script seems to assume that since it doesn't do error
checking. Unfortunately, bash automatically disables `errexit` when
calling a function from a conditional pipeline, like done in the `-s`
case:
if [ "${silent}" == true ]; then
if ! handle_build "${t}" &>"$log_file"; then
^^^^^^
this disables `errexit`
and `handle_build` ends with a `tar tvf` that always succeeds.
Adding error checking all over the place isn't really an option
as it would seriously obfuscate the code. Drop the conditional
pipeline instead and print the final error message from a `trap`
handler on the special ERR signal. This requires the `errtrace`
option as `trap`s aren't propagated to functions by default.
Since all outputs of `handle_build` are redirected to the build
log file, some file descriptor duplication magic is needed for
the handler to be able to write to the orignal stdout and stderr.

For the library `procfs`, the unit of values in `CpuTime` is ticks,
and we do not know how many ticks per second from metrics because the
`tps` in `CpuTime` is private.
But there are some implements in `CpuTime` for getting these values,
e.g., `user_ms()` for `user`, and `nice_ms()` for `nice`. With these
values, accurate time can be obtained.

Previously, it was not permitted to have neither an initrd nor an image.
However, this is the exact config to use for Secure Execution, where the
initrd is part of the image to be specified as `-kernel`. Require the
configuration of no initrd for Secure Execution.
Also
- remove redundant code for image/initrd checking -- no need to check in
`newQemuHypervisorConfig` (calling) when it is also checked in
`getInitrdAndImage` (called)
- use `QemuCCWVirtio` constant when possible

'make kata-tarball' sometimes fails early with:
cp: cannot create regular file '[...]/tools/packaging/kata-deploy/local-build/dockerbuild/install_yq.sh': File exists
This happens because all assets are built in parallel using the same
`kata-deploy-binaries-in-docker.sh` script, and thus all try to copy
the `install_yq.sh` script to the same location with the `cp` command.
This is a well known race condition that cannot be avoided without
serialization of `cp` invocations.
Move the copying of `install_yq.sh` to a separate script and ensure
it is called *before* parallel builds. Make the presence of the copy
a prerequisite for each sub-build so that they still can be triggered
individually. Update the GH release workflow to also call this script
before calling `kata-deploy-binaries-in-docker.sh`.

src/runtime/virtcontainers/hook/mock contains a simple example hook in Go.
The only thing this is used for is for some tests in
src/runtime/pkg/katautils/hook_test.go. It doesn't really have anything
to do with the rest of the virtcontainers package.
So, move it next to the test code that uses it.

Running unit tests should generally have minimal dependencies on
things outside the build tree. It *definitely* shouldn't modify
system wide things outside the build tree. Currently the runtime
"make test" target does so, though.
Several of the tests in src/runtime/pkg/katautils/hook_test.go require a
sample hook binary. They expect this hook in
/usr/bin/virtcontainers/bin/test/hook, so the makefile, as root, installs
the test binary to that location.
Go tests automatically run within the package's directory though, so
there's no need to use a system wide path. We can use a relative path to
the binary build within the tree just as easily.

The VC_BIN_DIR variable in the virtcontainers Makefile is almost unused.
It's used to generate TEST_BIN_DIR, and it's created in the install target.
However, we also create TEST_BIN_DIR, which is a subdirectory of VC_BIN_DIR
with mkdir -p, so it will necessarily create VC_BIN_DIR along the way.
So we can drop the unnecessary mkdir and expand the definition of
VC_BIN_DIR in the definition of TEST_BIN_DIR.

The check-go-test target passes the path to the mock hook test binary to
go-test.sh when it invokes it. But go-test.sh just calls run_go_test from
ci/lib.sh, which invokes a script from the tests repo *without* any
parameters.
That is, this parameter is ignored anyway, so remove it.
