cdoern 94df701512 Implement Podman Container Clone
podman container clone takes the id of an existing continer and creates a specgen from the given container's config
recreating all proper namespaces and overriding spec options like resource limits and the container name if given in the cli options

this command utilizes the common function DefineCreateFlags meaning that we can funnel as many create options as we want
into clone over time allowing the user to clone with as much or as little of the original config as they want.

container clone takes a second argument which is a new name and a third argument which is an image name to use instead of the original container's

the current supported flags are:

--destroy (remove the original container)
--name (new ctr name)
--cpus (sets cpu period and quota)
--cpuset-cpus
--cpu-period
--cpu-rt-period
--cpu-rt-runtime
--cpu-shares
--cpuset-mems
--memory
--run

Brent Baude 2a524fcaec fix healthcheck timeouts and ut8 coercion
this commit fixes two bugs and adds regression tests.

when getting healthcheck values from an image, if the image does not
have a timeout defined, this resulted in a 0 value for timeout.  The
default as described in the man pages is 30s.

when inspecting a container with a healthcheck command, a customer
observed that the &, <, and > characters were being converted into a
unicode escape value.  It turns out json marshalling will by default
coerce string values to ut8.

cdoern 289270375a Pod Security Option support
Added support for pod security options. These are applied to infra and passed down to the
containers as added (unless overridden).

Modified the inheritance process from infra, creating a new function Inherit() which reads the config, and marshals the compatible options into an intermediate struct `InfraInherit`
This is then unmarshaled into a container config and all of this is added to the CtrCreateOptions. Removes the need (mostly) for special additons which complicate the Container_create
code and pod creation.

down, involving new container CLI opts and specgen creating functions. What now happens is that both container and pod
cli options are populated in cmd and used to create a podSpecgen and a containerSpecgen. The process then goes as follows

FillOutSpecGen (infra) -> MapSpec (podOpts -> infraOpts) -> PodCreate -> MakePod -> createPodOptions -> NewPod -> CompleteSpec (infra) -> MakeContainer -> NewContainer -> newContainer -> AddInfra (to pod state)

Add --group-add keep-groups: suplimentary groups into container
Currently we have rootless users who want to leak their groups access
into containers, but this group access is only able to be pushed in by
a hard to find OCI Runtime annotation.  This PR makes this option a lot
more visable and hides the complexity within the podman client.

This option is only really needed for local rootless users. It makes
no sense for remote clients, and probably makes little sense for
rootfull containers.

Matthew Heon 6acd265306 Add --requires flag to podman run/create
Podman has, for a long time, had an internal concept of
dependency management, used mainly to ensure that pod infra
containers are started before any other container in the pod. We
also have the ability to recursively start these dependencies,
which we use to ensure that `podman start` on a container in a
pod will not fail because the infra container is stopped. We have
not, however, exposed these via the command line until now.

Add a `--requires` flag to `podman run` and `podman create` to
allow users to manually specify dependency containers. These
containers must be running before the container will start. Also,
make recursive starting with `podman start` default so we can
start these containers and their dependencies easily.

inspection to json-file.  These terms are used interchangably in other
locations in libpod/podman.

Paul Holzinger b5d1d89a37 Add shell completion with cobra
Allow automatic generation for shell completion scripts
with the internal cobra functions (requires v1.0.0+).

This should replace the handwritten completion scripts
and even adds support for fish. With this approach it is
less likley that completions and code are out of sync.

We can now create the scripts with
- podman completion bash
- podman completion zsh
- podman completion fish

To test the completion run:
source <(podman completion bash)

The same works for podman-remote and podman --remote and
it will complete your remote containers/images with
the correct endpoints values from --url/--connection.

The completion logic is written in go and provided by the
cobra library. The completion functions lives in
`cmd/podman/completion/completion.go`.

The unit test at cmd/podman/shell_completion_test.go checks
if each command and flag has an autocompletion function set.
This prevents that commands and flags have no shell completion set.

This commit does not replace the current autocompletion scripts.
