Previously, we use CreateConfig's Command to populate container
Command (which is used as CMD for Inspect and Commit).
Unfortunately, CreateConfig's Command is the container's full
command, including a prepend of Entrypoint - so we duplicate
Entrypoint for images that include it.
Maintain a separate UserCommand in CreateConfig that does not
include the entrypoint, and use that instead.

allow a container to run in a new cgroup namespace.
When running in a new cgroup namespace, the current cgroup appears to
be the root, so that there is no way for the container to access
cgroups outside of its own subtree.
By default it uses --cgroup=host to keep the previous behavior.
To create a new namespace, --cgroup=private must be provided.

When we first began writing Podman, we ran into a major issue
when implementing Inspect. Libpod deliberately does not tie its
internal data structures to Docker, and stores most information
about containers encoded within the OCI spec. However, Podman
must present a CLI compatible with Docker, which means it must
expose all the information in 'docker inspect' - most of which is
not contained in the OCI spec or libpod's Config struct.
Our solution at the time was the create artifact. We JSON'd the
complete CreateConfig (a parsed form of the CLI arguments to
'podman run') and stored it with the container, restoring it when
we needed to run commands that required the extra info.
Over the past month, I've been looking more at Inspect, and
refactored large portions of it into Libpod - generating them
from what we know about the OCI config and libpod's (now much
expanded, versus previously) container configuration. This path
comes close to completing the process, moving the last part of
inspect into libpod and removing the need for the create
artifact.
This improves libpod's compatability with non-Podman containers.
We no longer require an arbitrarily-formatted JSON blob to be
present to run inspect.

Docker CLI calls the healthcheck flags "--health-*", instead of
"--healthcheck-*".
Introduce the former, in order to keep compatibility, and alias
the later, in order to avoid breaking current usage.
Change "--healthcheck-*" to "--health-*" in the docs and tests.

If the image was built with "HEALTHCHECK NONE" then we should create a
container without healthcheck configuration. Otherwise executing the
healthcheck on the container will return "unhealthy" instead of the
correct error message that the container doesn't have a healthcheck.
We also ignore the healthcheck configuration if the command list is
empty or the command string is empty.

If the image doesn't provide any options, e.g. interval, timeout, etc.,
then apply the Docker defaults when creating the container. Otherwise
the defaults will be left 0 and podman doesn't schedule the healtcheck
service & timer for the container or incorrectly reports unhealthy state
when the check is executed.

Fix Docker CLI compatibility issue: the "--healthcheck-command" option
value should not be split but instead be passed as single string to
"CMD-SHELL", i.e. "/bin/sh -c <opt>".
On the other hand implement the same extension as is already available
for "--entrypoint", i.e. allow the option value to be a JSON array of
strings. This will make life easier for tools like podman-compose.
Updated "--healthcheck-command" option values in tests accordingly.

This flag passes the host environment into the container. The basic idea is to
leak all environment variables from the host into the container.
Environment variables from the image, and passed in via --env and --env-file
will override the host environment.

With StringSlice, we're seeing individual options added and
parsed separately, so `tmpfs:nosuid,nodev` turns into three tmpfs
mounts passed into pkg/sec (tmpfs:, nosuid, nodev). Swap to
StringArray to tell cobra this can't be split on commas.

the compilation demands of having libpod in main is a burden for the
remote client compilations. to combat this, we should move the use of
libpod structs, vars, constants, and functions into the adapter code
where it will only be compiled by the local client.
this should result in cleaner code organization and smaller binaries. it
should also help if we ever need to compile the remote client on
non-Linux operating systems natively (not cross-compiled).

Four of the healthcheck tests were completely broken. They
were written with the option '--healthcheck-cmd' which is
not an option (it should be '--healthcheck-command', with
'command' as a full word). The tests were merely checking
exit code, not error message, so of course they failed.
I have fixed the command line and added checks for the
expected diagnostic.
(Side note: do not write tests that check exit code but
nothing else. This should not need to be said).
One of the four tests was invalid: --healthcheck-interval 0.5s.
Per Brent:
initially i was going to restrict sub one-second intervals
That test has been removed. It would probably be a good idea
for a future PR to add some validation such as preventing
negative values, but that's left as an exercise for later.
Also: grammar fix in an error message.
Caught by my ginkgo log greasemonkey script, which
highlights 'Error' messages and grabbed my attention.
