This primarily served to protect us against shutting down the
Libpod runtime while operations (like creating a container) were
happening. However, it was very inconsistently implemented (a lot
of our longer-lived functions, like pulling images, just didn't
implement it at all...) and I'm not sure how much we really care
about this very-specific error case?
Removing it also removes a lot of potential deadlocks, which is
nice.

When removing a container created with a --volumes-from a container
created with a built in volume, we complain if the original container
still exists. Since this is an expected state, we should not complain
about it.

There is a problem with creating and storing the exit command when the
container was created. It only contains the options the container was
created with but NOT the options the container is started with. One
example would be a CNI network config. If I start a container once, then
change the cni config dir with `--cni-config-dir` ans start it a second
time it will start successfully. However the exit command still contains
the wrong `--cni-config-dir` because it was not updated.
To fix this we do not want to store the exit command at all. Instead we
create it every time the conmon process for the container is startet.
This guarantees us that the container cleanup process is startet with
the correct settings.

Make use of the new network interface in libpod.
This commit contains several breaking changes:
- podman network create only outputs the new network name and not file
path.
- podman network ls shows the network driver instead of the cni version
and plugins.
- podman network inspect outputs the new network struct and not the cni
conflist.
- The bindings and libpod api endpoints have been changed to use the new
network structure.
The container network status is stored in a new field in the state. The
status should be received with the new `c.getNetworkStatus`. This will
migrate the old status to the new format. Therefore old containers should
contine to work correctly in all cases even when network connect/
disconnect is used.
New features:
- podman network reload keeps the ip and mac for more than one network.
- podman container restore keeps the ip and mac for more than one
network.
- The network create compat endpoint can now use more than one ipam
config.
The man pages and the swagger doc are updated to reflect the latest
changes.

InfraContainer should go through the same creation process as regular containers. This change was from the cmd level
down, involving new container CLI opts and specgen creating functions. What now happens is that both container and pod
cli options are populated in cmd and used to create a podSpecgen and a containerSpecgen. The process then goes as follows
FillOutSpecGen (infra) -> MapSpec (podOpts -> infraOpts) -> PodCreate -> MakePod -> createPodOptions -> NewPod -> CompleteSpec (infra) -> MakeContainer -> NewContainer -> newContainer -> AddInfra (to pod state)

After #8906, there is a potential race condition in container
removal of running containers with `--rm`. Running containers
must first be stopped, which was changed to unlock the container
to allow commands like `podman ps` to continue to run while
stopping; however, this also means that the cleanup process can
potentially run before we re-lock, and remove the container from
under us, resulting in error messages from `podman rm`. The end
result is unchanged, the container is still cleanly removed, but
the `podman rm` command will seem to have failed.
Work around this by pinging the database after we stop the
container to make sure it still exists. If it doesn't, our job is
done and we can exit cleanly.

As part of a fix for an earlier bug (#5698) we added the ability
for Podman to chown volumes to correctly match the user running
in the container, even in adverse circumstances (where we don't
know the right UID/GID until very late in the process). However,
we only did this for volumes created automatically by a
`podman run` or `podman create`. Volumes made by
`podman volume create` do not get this chown, so their
permissions may not be correct. I've looked, and I don't think
there's a good reason not to do this chwon for all volumes the
first time the container is started.
I would prefer to do this as part of volume copy-up, but I don't
think that's really possible (copy-up happens earlier in the
process and we don't have a spec). There is a small chance, as
things stand, that a copy-up happens for one container and then
a chown for a second, unrelated container, but the odds of this
are astronomically small (we'd need a very close race between two
starting containers).

Move the core of renaming logic into the DB. This guarantees a
lot more atomicity than we have right now (our current solution,
removing the container from the DB and re-creating it, is *VERY*
not atomic and prone to leaving a corrupted state behind if
things go wrong. Moving things into the DB allows us to remove
most, but not all, of this - there's still a potential scenario
where the c/storage rename fails but the Podman rename succeeds,
and we end up with a mismatched state.

same networks could accidentally be added twice.

Secrets are blobs of data that are sensitive.
Currently, the only secret driver supported is filedriver, which means creating a secret stores it in base64 unencrypted in a file.
After creating a secret, a user can use the --secret flag to expose the secret inside the container at /run/secrets/[secretname]
This secret will not be commited to an image on a podman commit

Basic theory: We remove the container, but *only from the DB*.
We leave it in c/storage, we leave the lock allocated, we leave
it running (if it is). Then we create an identical container with
an altered name, and add that back to the database. Theoretically
we now have a renamed container.
The advantage of this approach is that it doesn't just apply to
rename - we can use this to make *any* configuration change to a
container that does not alter its container ID.
Potential problems are numerous. This process is *THOROUGHLY*
non-atomic at present - if you `kill -9` Podman mid-rename things
will be in a bad place, for example. Also, we can't rename
containers that can't be removed normally - IE, containers with
dependencies (pod infra containers, for example).
The largest potential improvement will be to move the majority of
the work into the DB, with a `RecreateContainer()` method - that
will add atomicity, and let us remove the container without
worrying about depencies and similar issues.
Potential problems: long-running processes that edit the DB and
may have an older version of the configuration around. Most
notable example is `podman run --rm` - the removal command needed
to be manually edited to avoid this one. This begins to get at
the heart of me not wanting to do this in the first place...
This provides CLI and API implementations for frontend, but no
tunnel implementation. It will be added in a future release (just
held back for time now - we need this in 3.0 and are running low
on time).
This is honestly kind of horrifying, but I think it will work.
