The on-failure restart option supports restarting only a given
number of times. To do this, we need one additional field in the
DB to track restart count (which conveniently fills a field in
Inspect we weren't populating), plus some plumbing logic.

This initial version does not support restart count, but it works

This field indicates that a container was explciitly stopped by
an API call, and did not exit naturally. It's used when
implementing restart policy for containers.

All IDs in libpod are stored as a full container ID. We can get a
container by full ID faster with GetContainer (which directly
retrieves) than LookupContainer (which finds a match, then
retrieves). No reason to use Lookup when we have full IDs present
and available.

We were never using it. It's actually a potentially quite sizable
field (very expensive to decode an array of structs!). Removing

This swaps the previous handling (parse all volume mounts on the
container and look for ones that might refer to named volumes)
for the new, explicit named volume lists stored per-container.
It also deprecates force-removing volumes that are in use. I
don't know how we want to handle this yet, but leaving containers
that depend on a volume that no longer exists is definitely not
correct.

We have an issue in the current implementation where the cleanup
process is not able to umount the storage as it is running in a
separate namespace.
Simplify the implementation for user namespaces by not using an
intermediate mount namespace. For doing it, we need to relax the
permissions on the parent directories and allow browsing
them. Containers that are running without a user namespace, will still
maintain mode 0700 on their directory.

We have a very high performance JSON library that doesn't need to
perform code generation. Let's use it instead of our questionably
performant, reflection-dependent deep copy library.
Most changes because some functions can now return errors.
Also converts cmd/podman to use jsoniter, instead of pkg/json,
for increased performance.

integration of healthcheck into create and run as well as inspect.
healthcheck enhancements are as follows:
* add the following options to create|run so that non-docker images can
define healthchecks at the container level.
* --healthcheck-command
* --healthcheck-retries
* --healthcheck-interval
* --healthcheck-start-period
* podman create|run --healthcheck-command=none disables healthcheck as
described by an image.
* the healthcheck itself and the healthcheck "history" can now be
observed in podman inspect
* added the wiring for healthcheck history which logs the health history
of the container, the current failed streak attempts, and log entries
for the last five attempts which themselves have start and stop times,
result, and a 500 character truncated (if needed) log of stderr/stdout.
The timings themselves are not implemented in this PR but will be in
future enablement (i.e. next).

Add the ability to manually run a container's healthcheck command.
This is only the first phase of implementing the healthcheck.
Subsequent pull requests will deal with the exposing the results and
history of healthchecks as well as the scheduling.

iFix builtin volumes to work with podman volume
Currently builtin volumes are not recored in podman volumes when
they are created automatically. This patch fixes this.
Remove container volumes when requested
Currently the --volume option on podman remove does nothing.
This will implement the changes needed to remove the volumes
if the user requests it.
When removing a volume make sure that no container uses the volume.

We try to keep c.config immutable, but Go doesn't really agree
with me that things other than strings and ints can be immutable,
so occasionally things like this slip through.
When unmarshalling the OCI spec from disk, do it into a separate
struct, to ensure we don't make lasting modifications to the
spec in the Container struct (which could affect container
restart).

Apply the default AppArmor profile at container initialization to cover
all possible code paths (i.e., podman-{start,run}) before executing the
runtime. This allows moving most of the logic into pkg/apparmor.
Also make the loading and application of the default AppArmor profile
versio-indepenent by checking for the `libpod-default-` prefix and
over-writing the profile in the run-time spec if needed.
The intitial run-time spec of the container differs a bit from the
applied one when having started the container, which results in
displaying a potentially outdated AppArmor profile when inspecting
a container. To fix that, load the container config from the file
system if present and use it to display the data.

The initial implementation to request the same IP address for a
container during a restore was based on environment variables
influencing CNI.
With this commit the IP address selection switches to Podman's internal
static IP API.
This commit does a comment change in libpod/container_easyjson.go to
avoid unnecessary re-generation of libpod/container_easyjson.go during
build as this fails in CI. The reason for this is that make sees that
libpod/container_easyjson.go needs to be re-created. The commit,
however, only changes a part of libpod/container.go which is marked as
'ffjson: skip'.

During an earlier bugfix, we swapped all instances of
ContainerConfig to Config, which was meant to fix some data we
were returning from Inspect. This unfortunately also renamed a
libpod internal struct for container configs. Undo the rename

When sharing a network namespace, containers should also share
resolv.conf and /etc/hosts in case a container process made
changes to either (for example, if I set up a VPN client in
container A and join container B to its network namespace, I
expect container B to use the DNS servers from A to ensure it can
see everything on the VPN).

/etc/resolv.conf and /etc/hosts should not be created and mounted when the
network is disabled.
We should not be calling the network setup and cleanup functions when it is
disabled either.
In doing this patch, I found that all of the bind mounts were particular to
Linux along with the generate functions, so I moved them to
container_internal_linux.go
Since we are checking if we are using a network namespace, we need to check
after the network namespaces has been created in the spec.

We are still requiring oci-systemd-hook to be installed in order to run
systemd within a container. This patch properly mounts
/sys/fs/cgroup/systemd/libpod_parent/libpod-UUID on /sys/fs/cgroup/systemd inside of container.
Since we need the UUID of the container, we needed to move Systemd to be a config option of the
container.

To work better with Kata containers, we need to delete() from the
OCI runtime as a part of cleanup, to ensure resources aren't
retained longer than they need to be.
To enable this, we need to add a new state to containers,
ContainerStateExited. Containers transition from
ContainerStateStopped to ContainerStateExited via cleanupRuntime
which is invoked as part of cleanup(). A container in the Exited
state is identical to Stopped, except it has been removed from
the OCI runtime and thus will be handled differently when
initializing the container.

FFJSON has serialization differences versus stock Go - namely, it
does not respect the MarshalText() and UnmarshalText() methods,
particularly on []byte, which causes incompatability with
pre-FFJSON containers which contained DNS servers.
EasyJSON does not have these issues, and might even be slightly
faster.
