Remove the container in ExecStop to make sure that Quadlet's adheres to
Podman's customizable stop signal/timeout. Certain programs ignore
SIGTERM which renders the services generated by Quadlet less user
friendly compared to the ones from podman-generate-systemd.
Previously, `systemctl stop` would just hang until systemd's stop
timeout is hit. Since `podman rm` also removes the CID file, the
additional `rm` can be removed. Note that `podman rm` will return
immediately if the specified CID file isn't present.
I am working on a short tutorial on Quadlet and hit the issue with a
simple container running `sleep`. `sleep` ignores SIGTERM and stopping
the service would take forever even with `PodmanArgs=--stop-timeout=0`.

The ReadOnly and the RunInit keys affect options that have a variable
default (configurable in containers.conf). This means we need to
handle them a bit differently in quadlet to allow overriding the
default. For example, we can't assume ReadOnly=false doesn't need to
add any argument because no argument may mean readonly=true if the default
is changed.
We now don't add any argument (leaving the default) if the key is not specified,
or we always add an argument (--foo or --foo=false) if the key is specified (overriding whatever the default is).

As outlined in #16076, a subsequent BARRIER *may* follow the READY
message sent by a container. To correctly imitate the behavior of
systemd's NOTIFY_SOCKET, the notify proxies span up by `kube play` must
hence process messages for the entirety of the workload.
We know that the workload is done and that all containers and pods have
exited when the service container exits. Hence, all proxies are closed
at that time.
The above changes imply that Podman runs for the entirety of the
workload and will henceforth act as the MAINPID when running inside of
systemd. Prior to this change, the service container acted as the
MAINPID which is now not possible anymore; Podman would be killed
immediately on exit of the service container and could not clean up.
The kube template now correctly transitions to in-active instead of
failed in systemd.

Quadlet was doing some custom handling of uid/gid remapping, originating
from pre --userns=auto support, including its own user for getting subuids
which kinda conflicts with the "container" user used for that.
This drops all the old support for id remapping in favour of a new set
of keys that more directly map to the podman run options.
We have essentially 3 modes now:
```
RemapUsers=manual
RemapUid=0:10000:10
RemapUid=10:20000:10
RemapGid=0:10000:10
RemapGid=10:20000:10
```
This maps to --uidmap and --gidmap options.
```
RemapUsers=auto
```
This maps to --userns=auto. But you can additionally specify RemapUid,
RemapGid and RemapUidSize which gets applied as options to the
--userns podman option.
```
RemapUsers=keep-id
```
This maps to --userns=keep-id and only works for user units.

This is much better for the systemd case becase we pass the journal
socket fds directly to the container. This means less copying of the
logs, but it also means the journal will correctly get the peer
process id when it tries to extract things like the name of what
is logging something.
With this we correctly name the logging process rather than claim
everything comes from conmon.

The notify proxy has a watcher to check whether the container has left

Truncate the container and pod ID files instead of throwing an error.
The main motivation is to prevent redundant work when starting systemd

This reverts commit c20abf12c7. In the
absence of `ExecStop` step, systemd will send the stop/kill signals to
the main PID while I asummed that systemd would jump directly to an
ExecStopPost step instead.

systemd.

Drop the ExecStop step to simplify the generated units a bit.
The extra ExecStopPost step was added by commit e5c3432944. If the
main PID (i.e., conmon) is killed, systemd will not execute ExecStop
(since the main PID is already down) but only execute the *Post steps.
Credits to the late Ulrich Obergfell for tracking this issue down; he is
missed.
The ExecStop step can safely be dropped since the Post step will take of
stopping (and removing) in any case.

When creating a new pod without the `--name` flag, e.g.:
`podman pod create foobar`
it will get the name `foobar` implicitly and this will be recorded as the in the
`podCreateArgs`. Unfortunately, the implicit name only works if it appears as
the **last** argument of the startup command.
With 6e2e3a78ed we started appending the pod
security policy to the startCommand, resulting in the following `ExecStartPre=`
line:
```
/usr/bin/podman pod create --infra-conmon-pidfile %t/pod-foobar.pid --pod-id-file %t/pod-foobar.pod-id foobar --exit-policy=stop
```
This fails to launch, as the `pod create` command expects only a single
non-flag parameter, but it assumes that `exit-policy=stop` is a second and
terminates immediately instead.
This fixes https://github.com/containers/podman/issues/15592
