This `--config` option was initially added here:
4e4c3e3dbf
Under the hood this simply modifies env to set DOCKER_CONFIG=<passed
in string>
The DOCKER_CONFIG env var is used as a directory that contains
multiple config files... of which podman and container libs probably
only use `$DIR/config.json`.
See: https://docs.docker.com/reference/cli/docker/#environment-variables
The old CMD and help text was misleading... if we point the at a
regular file we can see errors like:
```
$ touch /tmp/foo/tmpcr9zrx71
$ /bin/podman --config /tmp/foo/tmpcr9zrx71 build -t foobar:latest
Error: creating build container: initializing source docker://quay.io/centos/centos:stream9: getting username and password: reading JSON file "/tmp/foo/tmpcr9zrx71/config.json": open /tmp/foo/tmpcr9zrx71/config.json: not a directory
```
^^ In this case we had created `/tmp/foo/tmpcr9zrx71` as a regular file.

When a user specifies a invalid connection in CONTAINER_CONNECTION then
podman should return a proper error saying so. Currently it ignored the
error and in rootFlags() just exited early with defining any flags. This
caused a panic then when trying to use the flags later.
In order to address this first store the connection error in the
PodmanConfig struct and not abort right away during flag setup. This is
important as the user might have specified a flag with a valid remote
connection. As such we check all flags and only when none were given we
return the connection error.
Also while at it I noticed that the default connection reported via
podman --help was wrong as it only used the old containers.conf field
for it and did not consider the podman-connections.json default.
New regression tests have been added to make sure it behaves correctly.
This fixes the problem reported in the PR #22997.

The expectation with --cgroups=disabled is that the current cgroup is

Currently the --cgroups=disabled is passed directly to the OCI

We now no longer write containers.conf, instead system connections and
farms are written to a new file called podman-connections.conf.
This is a major rework and I had to change a lot of things to get this
to compile again with my c/common changes.
It is a breaking change for users as connections/farms added before this
commit can now no longer be removed or modified directly. However because
the logic keeps reading from containers.conf the old connections can
still be used to connect to a remote host.

The processing and setting of the static and volume directories was
scattered across the code base (including c/common) leading to subtle
errors that surfaced in #19938.
There were multiple issues that I try to summarize below:
- c/common loaded the graphroot from c/storage to set the defaults for
static and volume dir. That ignored Podman's --root flag and
surfaced in #19938 and other bugs. c/common does not set the
defaults anymore which gives Podman the ability to detect when the
user/admin configured a custom directory (not empty value).
- When parsing the CLI, Podman (ab)uses containers.conf structures to
set the defaults but also to override them in case the user specified
a flag. The --root flag overrode the static dir which is wrong and
broke a couple of use cases. Now there is a dedicated field for in
the "PodmanConfig" which also includes a containers.conf struct.
- The defaults for static and volume dir and now being set correctly
and adhere to --root.
- The CONTAINERS_CONF_OVERRIDE env variable has not been passed to the
cleanup process. I believe that _all_ env variables should be passed
to conmon to avoid such subtle bugs.
Overall I find that the code and logic is scattered and hard to
understand and follow. I refrained from larger refactorings as I really
just want to get #19938 fixed and then go back to other priorities.
https://github.com/containers/common/pull/1659 broke three pkg/machine
tests. Those have been commented out until getting fixed.

The --module can only be parsed on the root level. It cannot work on
the command level, because it must be "manually" parsed on init() to
make sure the specified configuration files/modules are loaded prior to
parsing the flags via Cobra.
Hence move --module from the "persistent" to the "local" flags which
will yield an error instead of doing nothing when being specified on the
command level:
```
$ ./bin/podman run --module=foo.conf --rm alpine
Error: unknown flag: --module
See 'podman run --help'
```

Support a new concept in containers.conf called "modules". A "module"
is a containers.conf file located at a specific directory. More than
one module can be loaded in the specified order, following existing
override semantics.
There are three directories to load modules from:
- $CONFIG_HOME/containers/containers.conf.modules
- /etc/containers/containers.conf.modules
- /usr/share/containers/containers.conf.modules
With CONFIG_HOME pointing to $HOME/.config or, if set, $XDG_CONFIG_HOME.
Absolute paths will be loaded as is, relative paths will be resolved
relative to the three directories above allowing for admin configs
(/etc/) to override system configs (/usr/share/) and user configs
($CONFIG_HOME) to override admin configs.

The `--network-cmd-path` CLI option only affects rootless networks using `slirp4netns(1)`, not `pasta(1)`.

However, since this wasn't implemented yet we can't deprecate `--network-cmd-path` as of now. Adding a note anyway.

If the run errors, cobra does not execute post runs. It is a somehow
known issue (https://github.com/spf13/cobra/issues/914) but problematic
for Podmand as the runtime is shutdown during post run.
Since some commands overwrite the post run and a general lack in cobra
of post runs on errors, move the shutting down the engines directly into
Execute. Fixing the issue may fix a number of flakes.
Note that the shutdowns are NOPs for the remote client.

Use `Default()` instead of re-loading containers.conf.
Also rework how the containers.conf objects are handled for parsing the

which ultimately led to various bugs and test failues.
To address the issue, separate the defaults from the values from the CLI
and properly name the fields to make the semantics less ambiguous.

implement new ssh interface into podman
this completely redesigns the entire functionality of podman image scp,
podman system connection add, and podman --remote. All references to golang.org/x/crypto/ssh
have been moved to common as have native ssh/scp execs and the new usage of the sftp package.
this PR adds a global flag, --ssh to podman which has two valid inputs `golang` and `native` where golang is the default.
Users should not notice any difference in their everyday workflows if they continue using the golang option. UNLESS they have been using an improperly verified ssh key, this will now fail. This is because podman was incorrectly using the
ssh callback method to IGNORE the ssh known hosts file which is very insecure and golang tells you not yo use this in production.
The native paths allows for immense flexibility, with a new containers.conf field `SSH_CONFIG` that specifies a specific ssh config file to be used in all operations. Else the users ~/.ssh/config file will be used.
podman --remote currently only uses the golang path, given its deep interconnection with dialing multiple clients and urls.
My goal after this PR is to go back and abstract the idea of podman --remote from golang's dialed clients, as it should not be so intrinsically connected. Overall, this is a v1 of a long process of offering native ssh, and one that covers some good ground with podman system connection add and podman image scp.
