Add support to auto-update containers running in systemd units as
generated with `podman generate systemd --new`.
`podman auto-update` looks up containers with a specified
"io.containers.autoupdate" label (i.e., the auto-update policy).
If the label is present and set to "image", Podman reaches out to the
corresponding registry to check if the image has been updated. We
consider an image to be updated if the digest in the local storage is
different than the one of the remote image. If an image must be
updated, Podman pulls it down and restarts the container. Note that the
restarting sequence relies on systemd.
At container-creation time, Podman looks up the "PODMAN_SYSTEMD_UNIT"
environment variables and stores it verbatim in the container's label.
This variable is now set by all systemd units generated by
`podman-generate-systemd` and is set to `%n` (i.e., the name of systemd
unit starting the container). This data is then being used in the
auto-update sequence to instruct systemd (via DBUS) to restart the unit
and hence to restart the container.
Note that this implementation of auto-updates relies on systemd and
requires a fully-qualified image reference to be used to create the
container. This enforcement is necessary to know which image to
actually check and pull. If we used an image ID, we would not know
which image to check/pull anymore.

We attempted to share all logic for parsing labels and
environment variables, which on the surface makes lots of sense
(both are formatted key=value so parsing logic should be
identical) but has begun to fall apart now that we have added
additional logic to environment variable handling. Environment
variables that are unset, for example, are looked up against
environment variables set for the process. We don't want this for
labels, so we have to split parsing logic.

consumers of the api remarked how they would prefer a more strongly typed data structure from list containers oon the libpod side of things. for example, events should be consumable and consistent timestamps. also, for the sake of compatibility, it is helpful to have the json named atttributes for Id to not be ID.
listcontainers on the libpod side no longer strongly uses the the ps cli to obtain information but we do benefit from turning on the ability to list the last X containers, something CLI does not have yet. we also flipped the bit on defaulting to truncated output in the return.
thanks to the efforts of the cockpit team to help us here.

Relax the os/arch checks when creating a container and only info-log
mismatches instead of erroring out. There are too many images used
in the wild which do not set their arch correctly correctly. Erroring
out has hit users sufficiently enough to justify relaxing the errors
and only log to at least inform the users and image vendors.

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.

The helper function we use for signal name mapping does not
check for negative numbers nor invalid (too-high) ones. This
can yield unexpected error messages:
# podman kill -s -1 foo
ERRO[0000] unknown signal "18446744073709551615"
This PR introduces a small wrapper for it that:
1) Strips off a leading dash, allowing '-1' or '-HUP'
as valid inputs; and
2) Rejects numbers <1 or >64 (SIGRTMAX)
Also adds a test suite checking signal handling as well as
ensuring that invalid signals are rejected by the command line.

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 Libpod removes a container, there is the possibility that
removal will not fully succeed. The most notable problems are
storage issues, where the container cannot be removed from
c/storage.
When this occurs, we were faced with a choice. We can keep the
container in the state, appearing in `podman ps` and available for
other API operations, but likely unable to do any of them as it's
been partially removed. Or we can remove it very early and clean
up after it's already gone. We have, until now, used the second
approach.
The problem that arises is intermittent problems removing
storage. We end up removing a container, failing to remove its
storage, and ending up with a container permanently stuck in
c/storage that we can't remove with the normal Podman CLI, can't
use the name of, and generally can't interact with. A notable
cause is when Podman is hit by a SIGKILL midway through removal,
which can consistently cause `podman rm` to fail to remove
storage.
We now add a new state for containers that are in the process of
being removed, ContainerStateRemoving. We set this at the
beginning of the removal process. It notifies Podman that the
container cannot be used anymore, but preserves it in the DB
until it is fully removed. This will allow Remove to be run on
these containers again, which should successfully remove storage
if it fails.

As it stands, createconfig is a huge struct. This works fine when the only caller is when we create a container with a fully created config. However, if we wish to share code for security and namespace configuration, a single large struct becomes unweildy, as well as difficult to configure with the single createConfigToOCISpec function.
This PR breaks up namespace and security configuration into their own structs, with the eventual goal of allowing the namespace/security fields to be configured by the pod create cli, and allow the infra container to share this with the pod's containers.
