Add a way to keep play kube running in the foreground and terminating all pods
after receiving a a SIGINT or SIGTERM signal. The pods will also be
cleaned up after the containers in it have exited.
If an error occurrs during kube play, any resources created till the
error point will be cleane up also.
Add tests for the various scenarios.

Only enforce the passthrough log driver for Quadlet. Commit 68fbebf
introduced a regression on the `podman-kube@` template as `podman logs`
stopped working and settings from containers.conf were ignored.

Commit 2f29639bd3 added a UX improvement to cleanup/teardown when
running the specified YAML has failed. However, the teardown happens
unconditionally such that rerunning the same YAML file will teardown the
previously created workload instead of just failing with a name-conflict
error (e.g., "pod already exists"). The regression popped up testing
the Ansible system role with Podman v4.4.0.
For now, do not teardown at all on error to quickly fix this regression
for the upcoming Podman v4.4.1 release. The UX improvement is still
desired but must be conditional and only happen on newly created
resources, which probably requires moving it down to the backend.

Reasoning
---------
When the log-driver is passthrough, the journal socket is passed to the containers as-is which has two advantages:
1. journald can see who the actual sender of the log event is,
rather than thinking everything comes from the conmon process
2. conmon will not have to copy all the log data
Code Changes
------------
If log-driver was not set by the user and service-container is set use
passthrough as the default log-driver
Update the system tests
- explicitly set logdriver in sdnotify and play tests
- podman-kube template test: Verify the default log driver for service-container

If an error happening while playing a kube yaml,
clean up any pods, containers, and volumes that might
have been created before the error was hit.
This improves the user experience for when they go to
re-run the same yaml with their fixes and podman doesn't
complain about any existing workloads from the previously
failed run.
Suppress the clean up output when clean up happens after an
error as the user doesn't need to see or know about that.

Up - do not fail if volume already exists, use the existing one
Down - allow the user to remove the volume by passing --force

Package `io/ioutil` was deprecated in golang 1.16, preventing podman from
building under Fedora 37. Fortunately, functionality identical
replacements are provided by the packages `io` and `os`. Replace all
usage of all `io/ioutil` symbols with appropriate substitutions
according to the golang docs.

`podman kube play` can create pods and containers from YAML
read from a URL poiniting to a YAML file.
For example: `podman kube play https://example.com/demo.yml`.
`podman kube down` can also teardown pods and containers created
from that YAML file by also reading YAML from a URL, provided the
YAML file the URL points to has not been changed or altered since
it was used to create pods and containers

"podman kube generate" creates Kubernetes YAML from Podman containers,
pods or volumes. Users will still be able to use "podman generate
kube" as an alias of "kube generate".

Integrate sd-notify policies into `kube play`. The policies can be
configured for all contianers via the `io.containers.sdnotify`
annotation or for indidivual containers via the
`io.containers.sdnotify/$name` annotation.
The `kube play` process will wait for all containers to be ready by
waiting for the individual `READY=1` messages which are received via
the `pkg/systemd/notifyproxy` proxy mechanism.
Also update the simple "container" sd-notify test as it did not fully
test the expected behavior which became obvious when adding the new
tests.

The "podman kube down" reads in a structured file of
Kubernetes YAML and removes pods based on the Kubernetes kind described in the YAML,
similiar to "podman play kube --down". Users will still be able to use
"podman play kube --down" and "podman kube play --down" to
perform the same function.

When podman kube play was added the endpoint for the kube play/play kube
commands was switched from the "play kube" endpoint to the new "kube play"
endpoint. This caused issues with the remote client, requiring the need
to use the "play kube" endpoint again in order to avoid these issues.

The "podman kube play" command is designed to be a replacement for the
"podman play kube" command.
It performs the same function as "play kube" while also still working with the same flags and options.
The "podman play kube" command is still functional as an alias of "kube play".
