When running a single podman logs this is not really important since we
will exit when we finish reading the logs. However for the system
service this is very important. Leaking goroutines will cause an
increased memory and CPU ussage over time.
Both the the event and log backend have goroutine leaks with both the
file and journald drivers.
The journald backend has the problem that journal.Wait(IndefiniteWait)
will block until we get a new journald event. So when a client closes
the connection the goroutine would still wait until there is a new
journal entry. To fix this we just wait for a maximum of 5 seconds,
after that we can check if the client connection was closed and exit
correctly in this case.
For the file backend we can fix this by waiting for either the log line
or context cancel at the same time. Currently it would block waiting for
new log lines and only check afterwards if the client closed the
connection and thus hang forever if there are no new log lines.
[NO NEW TESTS NEEDED] I am open to ideas how we can test memory leaks in
CI.
To test manually run a container like this:
`podman run --log-driver $driver --name test -d alpine sh -c 'i=1; while [ "$i" -ne 1000 ]; do echo "line $i"; i=$((i + 1)); done; sleep inf'`
where `$driver` can be either `journald` or `k8s-file`.
Then start the podman system service and use:
`curl -m 1 --output - --unix-socket $XDG_RUNTIME_DIR/podman/podman.sock -v 'http://d/containers/test/logs?follow=1&since=0&stderr=1&stdout=1' &>/dev/null`
to get the logs from the API and then it closes the connection after 1 second.
Now run the curl command several times and check the memory usage of the service.

Previously, if a container had healthchecks disabled in the
docker-compose.yml file and the user did a `podman inspect <container>`,
they would have an incorrect output:
```
"Healthcheck":{
"Test":[
"CMD-SHELL",
"NONE"
],
"Interval":30000000000,
"Timeout":30000000000,

```
After a quick change, the correct output is now the result:
```
"Healthcheck":{
"Test":[
"NONE"

}
```
Additionally, I extracted the hard-coded strings that were used for
comparisons into constants in `libpod/define` to prevent a similar issue

currently, setting any sort of resource limit in a pod does nothing. With the newly refactored creation process in c/common, podman ca now set resources at a pod level
meaning that resource related flags can now be exposed to podman pod create.
cgroupfs and systemd are both supported with varying completion. cgroupfs is a much simpler process and one that is virtually complete for all resource types, the flags now just need to be added. systemd on the other hand
has to be handeled via the dbus api meaning that the limits need to be passed as recognized properties to systemd. The properties added so far are the ones that podman pod create supports as well as `cpuset-mems` as this will
be the next flag I work on.

This bug was introduced in https://github.com/containers/podman/pull/8906.
When we use 'podman rm/restart/stop/kill etc...' command to
the container running with --rm, the OCI runtime directory
remains at /run/<runtime name> (root user) or
/run/user/<user id>/<runtime name> (rootless user).
This bug could cause other bugs.
For example, when we checkpoint the container running with
--rm (podman checkpoint --export) and restore it
(podman restore --import) with crun, error message
"Error: OCI runtime error: crun: container `<container id>`
already exists" is outputted.
This error is caused by an attempt to restore the container with
the same container ID as the remaining OCI runtime's container ID.
Therefore, I fix that the cleanupRuntime() function runs to
remove the OCI runtime directory,
even if the container has already been removed by --rm option.

Libpod requires that all volumes are stored in the libpod db. Because
volume plugins can be created outside of podman, it will not show all
available plugins. This podman volume reload command allows users to
sync the libpod db with their external volume plugins. All new volumes
from the plugin are also created in the libpod db and when a volume from
the db no longer exists it will be removed if possible.
There are some problems:
- naming conflicts, in this case we only use the first volume we found.
This is not deterministic.
- race conditions, we have no control over the volume plugins. It is
possible that the volumes changed while we run this command.

Firstly: don't prune exit codes after a refresh - instead, clear
the table entirely. We are guaranteed that all containers are
gone after a refresh, we should not worry about exit codes given
this.
Secondly: alter the way pruning was done. We were updating the DB
by calling Update from within an existing View, and stacking an
RW transaction on top of an existing RO one seems dodgy; further,
modifying a bucket while iterating over it with ForEach is
undefined behavior.
Hopefully this will resolve our CI issues.

This commit addresses three intertwined bugs to fix an issue when using
Gitlab runner on Podman. The three bug fixes are not split into
separate commits as tests won't pass otherwise; avoidable noise when
bisecting future issues.
1) Podman conflated states: even when asking to wait for the `exited`
state, Podman returned as soon as a container transitioned to
`stopped`. The issues surfaced in Gitlab tests to fail [1] as
`conmon`'s buffers have not (yet) been emptied when attaching to a
container right after a wait. The race window was extremely narrow,
and I only managed to reproduce with the Gitlab runner [1] unit
tests.
2) The clearer separation between `exited` and `stopped` revealed a race
condition predating the changes. If a container is configured for
autoremoval (e.g., via `run --rm`), the "run" process competes with
the "cleanup" process running in the background. The window of the
race condition was sufficiently large that the "cleanup" process has
already removed the container and storage before the "run" process
could read the exit code and hence waited indefinitely.
Address the exit-code race condition by recording exit codes in the
main libpod database. Exit codes can now be read from a database.
When waiting for a container to exit, Podman first waits for the
container to transition to `exited` and will then query the database
for its exit code. Outdated exit codes are pruned during cleanup
(i.e., non-performance critical) and when refreshing the database
after a reboot. An exit code is considered outdated when it is older
than 5 minutes.
While the race condition predates this change, the waiting process
has apparently always been fast enough in catching the exit code due
to issue 1): `exited` and `stopped` were conflated. The waiting
process hence caught the exit code after the container transitioned
to `stopped` but before it `exited` and got removed.
3) With 1) and 2), Podman is now waiting for a container to properly
transition to the `exited` state. Some tests did not pass after 1)
and 2) which revealed the third bug: `conmon` was executed with its
working directory pointing to the OCI runtime bundle of the
container. The changed working directory broke resolving relative
paths in the "cleanup" process. The "cleanup" process error'ed
before actually cleaning up the container and waiting "main" process
ran indefinitely - or until hitting a timeout. Fix the issue by
executing `conmon` with the same working directory as Podman.
Note that fixing 3) *may* address a number of issues we have seen in the
past where for *some* reason cleanup processes did not fire.
