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.

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.

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).

The --read-only-tmpfs option caused podman to mount tmpfs on /run, /tmp, /var/tmp
if the container is running int read-only mode.
The default is true, so you would need to execute a command like
--read-only --read-only-tmpfs=false to turn off this behaviour.

add the ability to create and run containers via the podman-remote
client.
we now create an intermediate layer from the the create/run cli flags.
the intermediate layer can be converted into a createconfig or into a
varlink struct. Once transported, the varlink struct can be converted
back to an intermediate layer and then to a createconfig.
remote terminals are not supported yet.

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.

podman will not start a transient service and timer for healthchecks.
this handles the tracking of the timing for health checks.
added the 'started' status which represents the time that a container is
in its start-period.
the systemd timing can be disabled with an env variable of
DISABLE_HC_SYSTEMD="true".
added filter for ps where --filter health=[starting, healthy, unhealthy]
can now be used.

Remove hardcoded '(default: true)' strings from bool flags,
and '(default this-or-that)' from string flags.
First because it's unmaintainable duplication that would cause
confusion should someone ever change the default and not notice
the message.
Second, because cobra[1] already prints '(default XXXX)' for
all options with non-false non-nil default. So in each of
these cases, current podman help behavior is:
$ podman login --help
...
--tls-verify Require HTTPS ... (default: true) (default true)
This PR eliminates that duplication.

The only nontrivial one of these is start.go, where the default
for sigProxy depends on the --attach flag. Solution: change
the command-line default to false, and implement the new
conditional default in logic. Bonus: removed unnecessary
check, because now if sigProxy is set without --attach,
we can guarantee that it was done by the user. But please
pay close scrutiny to this particular section in case
there's something I missed.

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).

Currently in podman if a user specifies a command that does not exist
the tool shows the help information. This patch changes it to show
information like:
$ ./bin/podman foobar
Error: unrecognized command 'podman foobar'
Try 'podman --help' for more information.
$ ./bin/podman volume foobar
Error: unrecognized command `podman volume foobar`
Try 'podman volume --help' for more information.
$ ./bin/podman container foobar
Error: unrecognized command `podman container foobar`

Make more general-purpose: instead of hardcoding a list
of known subcommands, and duplicating sed pipelines for
each, rely on 'podman help' itself to tell us which
podman commands have subcommands; and examine each
in turn. Should there ever be new subcommands, this
will identify and test them.
A special case is needed for 'podman image trust', whose
documentation format doesn't match the others.
The change to `common.go` fixes an inconsistency: the
Usage message for commands with subcommands had an
unnecessary blank line, making it harder to parse
automatically. This simply produces consistent
Usage messages for all podman commands.
This script will not pass until #2480 is merged.
After that, the goal is to add this as a CI hook.

Several podman commands accept no subcommands. Some
of those were not actually checking, though, which
could lead to user confusion. Added validation where
missing; and, refactored to minimize duplication.
(Side note: I decided against using cobra.NoArgs
because its error message, "unknown command",
misleadingly implies that there are known ones).

Add support for executing an init binary as PID 1 in a container to
forward signals and reap processes. When the `--init` flag is set for
podman-create or podman-run, the init binary is bind-mounted to
`/dev/init` in the container and "/dev/init --" is prepended to the
container's command.
The default base path of the container-init binary is `/usr/libexec/podman`
while the default binary is catatonit [1]. This default can be changed
permanently via the `init_path` field in the `libpod.conf` configuration
file (which is recommended for packaging) or temporarily via the
`--init-path` flag of podman-create and podman-run.
