This is mostly used with Systemd, which really wants to manage
CGroups itself when managing containers via unit file.

Use a consistent format for description of the <size><unit> flags.
Also, avoid backticks for /dev/shm, as that's interpreted as the format
by the flag parsing lib.

Udica is adding new features to allow users to define container process
and file types. This would allow us to setup trusted communications channels
between multiple security domains. ContainerA -> ContainerB -> ContainerC
Add tests to make sure users can change file types

Requirement from https://github.com/containers/libpod/issues/3575#issuecomment-512238393
Added --pull for podman create and pull to match the newly added flag in docker CLI.
`missing`: default value, podman will pull the image if it does not exist in the local.
`always`: podman will always pull the image.
`never`: podman will never pull the image.

This PR makes --dns, --dns-option, --dns-search, and --network not set to host flag mutually exclusive for podman build and create. Returns conflict error if both flags are set.

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.

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.

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.

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).
