The --ignore flag lets Podman ignore errors when a specified container
does not exist (anymore). That's a nice addition to generic services
generated via the --new flag. Those services create new containers and
can hence allows user to manually remove a container; may it only be by
accident.
The important part of using the --ignore flag is that Podman will exit 0
which plays nicer with most restart policies; a non-zero exit may yield
systemd to restart the entire service which is arguably wrong if the
user manually deletes the container.
If desired, users can still alter the generated files.

Make the signal test more robust by just checking that the container's
exit code is non-zero. There are two possible exit codes (i.e., 130 and
137) depending on how the container is being killed, which is likely
responsible for CI flakes.

Implement a policy for selecting a seccomp profile. In addition to the
default behaviour (default profile unless --security-opt seccomp is set)
add a second policy doing a lookup in the image annotation.
If the image has the "io.containers.seccomp.profile" set its value will be
interpreted as a seccomp profile. The policy can be selected via the
new --seccomp-policy CLI flag.
Once the containers.conf support is merged into libpod, we can add an
option there as well.
Note that this feature is marked as experimental and may change in the
future.

Add a --new flag to podman-generate-systemd to create a new container
via podman-run instead of starting an existing container.
Creating a new container presents the challenge to find a reverse
mapping from a container to the CLI flags it can be created with. We
are doing this via `(Container).Config.CreateCommand` field, which
includes a copy of the process' command from procFS at creating time.
This field may not be useful when the container was not created via the
Podman CLI (e.g., via a Python script). Hence, we do not guarantee the
correctness of the generated files.

Currently, if a user requests the size on a container (inspect --size -t container),
the SizeRw does not show up if the value is 0. It's because InspectContainerData is
defined as int64 and there is an omit when empty.
We do want to display it even if the value is empty. I have changed the type of SizeRw to be a pointer to an int64 instead of an int64. It will allow us todistinguish the empty value to the missing value.
I updated the test "podman inspect container with size" to ensure we check thatSizeRw is displayed correctly.

Store the full command plus arguments of the process the container has
been created with. Expose this data as a `Config.CreateCommand` field
in the container-inspect data as well.
This information can be useful for debugging, as we can find out which
command has created the container, and, if being created via the Podman
CLI, we know exactly with which flags the container has been created
with.
The immediate motivation for this change is to use this information for
`podman-generate-systemd` to generate systemd-service files that allow
for creating new containers (in contrast to only starting existing
ones).

When doing a checkpoint with --export the root file-system diff was not
working as expected. Instead of getting the changes from the running
container to the highest storage layer it got the changes from the
highest layer to that parent's layer. For a one layer container this
could mean that the complete root file-system is part of the checkpoint.
With this commit this changes to use the same functionality as 'podman
diff'. This actually enables to correctly diff the root file-system
including tracking deleted files.
This also removes the non-working helper functions from libpod/diff.go.

The way we were trying to parse was very broken. I originally
attempted to use Buildah's Dockerfile parser here, but dealing
with it (and convincing it to accept only a limited subset, and
only one instruction at a time) was challenging, so I rewrote a
subset of Dockerfile parsing. This should handle most common
cases well, though there are definitely unhandled edge cases for
ENV and LABEL.

Trying to checkpoint a container started with --rm works, but it makes
no sense as the container, including the checkpoint, will be deleted
after writing the checkpoint. This commit inhibits checkpointing
containers started with '--rm' unless '--export' is used. If the
checkpoint is exported it can easily be restored from the exported
checkpoint, even if '--rm' is used. To restore a container from a
checkpoint it is even necessary to manually run 'podman rm' if the
container is not started with '--rm'.

Add an --ignore flag to podman rm and stop. When specified, Podman will
ignore "no such {container,pod}" errors that occur when a specified
container/pod is not present in the store (anymore). The motivation
behind adding this flag is to write more robust systemd services using
Podman. A user might have manually decided to remove a container/pod
which would lead to a failure during the `ExecStop` directive of a
systemd service referencing that container/pod.
