Vikas Goel 89b415ba37 Comply to Kubernetes specifications for annotation size.
An annotation is a pair of key-value. The key has two parts, viz. a name and an optional prefix in DNS format.

The limitations on name is 63, prefix 253 chars. The limitation on total size of all key+value pairs combined is 256KB.

Jake Correnti 7b54fd84ec Add `--no-trunc` flag to maintain original annotation length
Adds a `--no-trunc` flag to `podman kube generate` preventing the
annotations from being trimmed at 63 characters. However, due to
the fact the annotations will not be trimmed, any annotation that is
longer than 63 characters means this YAML will no longer be Kubernetes
compatible. However, these YAML files can still be used with `podman
kube play` due to the addition of the new flag below.

Adds a `--no-trunc` flag to `podman kube play` supporting YAML files with
annotations that were not truncated to the Kubernetes maximum length of
63 characters.

Valentin Rothberg 08b0d93ea3 kube play: exit-code propagation
Implement means for reflecting failed containers (i.e., those having
exited non-zero) to better integrate `kube play` with systemd.  The
idea is to have the main PID of `kube play` exit non-zero in a
configurable way such that systemd's restart policies can kick in.

When using the default sdnotify-notify policy, the service container
acts as the main PID to further reduce the resource footprint.  In that
case, before stopping the service container, Podman will lookup the exit
codes of all non-infra containers.  The service will then behave
according to the following three exit-code policies:

 - `none`: exit 0 and ignore containers (default)
 - `any`: exit non-zero if _any_ container did
 - `all`: exit non-zero if _all_ containers did

The upper values can be passed via a hidden `kube play
--service-exit-code-propagation` flag which can be used by tests and
later on by Quadlet.

In case Podman acts as the main PID (i.e., when at least one container
runs with an sdnotify-policy other than "ignore"), Podman will continue
to wait for the service container to exit and reflect its exit code.

Note that this commit also fixes a long-standing annoyance of the
service container exiting non-zero.  The underlying issue was that the
service container had been stopped with SIGKILL instead of SIGTERM and
hence exited non-zero.  Fixing that was a prerequisite for the exit-code
propagation to work but also improves the integration of `kube play`
with systemd and hence Quadlet with systemd.

Valentin Rothberg 83367a6b3b kube play: do not teardown unconditionally on error
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.

Ygal Blum 68fbebfacc Kube Play: use passthrough as the default log-driver if service-container is set
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

Urvashi Mohnani 2f29639bd3 Cleanup kube play workloads if error happens
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.
