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.

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.

in the case of the remote-client, it was decided to hide the latest
flag to avoid confusion for end-users on what the "last" container,
volume, or pod are.

Prior, a pod would have to be started immediately when created, leading to confusion about what a pod state should be immediately after creation. The problem was podman run --pod ... would error out if the infra container wasn't started (as it is a dependency). Fix this by allowing for recursive start, where each of the container's dependencies are started prior to the new container. This is only applied to the case where a new container is attached to a pod.
Also rework container_api Start, StartAndAttach, and Init functions, as there was some duplicated code, which made addressing the problem easier to fix.

Add support for podman volume and its subcommands.
The commands supported are:
podman volume create
podman volume inspect
podman volume ls
podman volume rm
podman volume prune
This is a tool to manage volumes used by podman. For now it only handle
named volumes, but eventually it will handle all volumes used by podman.

We now can remove a paused container by sending it a kill signal while it
is paused. We then unpause the container and it is immediately killed.
Also, reworked how the parallelWorker results are handled to provide a
more consistent approach to how each subcommand implements it. It also
fixes a bug where if one container errors, the error message is duplicated
when printed out.

Prior, we were stopping containers serially. So if a container had a default
timeout of 10 seconds and there were five containers being stopped, the operation
would take roughly 50 seconds. If we stop these containers in parallel, the operation
should be roughly 10 seconds and change which is a significant speed up at scale.

333ab8c2 (Fix podman hangs when detecting startup error in container
attached mode, 2018-06-27, #1010) addressed this with a deferred
drain. This commit adjusts that approach to use a single select to
cover "have we been canceled?", "has there been a resize signal?", and
(when we have one) "can we write the most recent resize event to the
resize channel?".
A side benefit to this approach is that if we have a slow resize
consumer and several resize signals, the resizeTty function will keep
updating its local resizeEvent. Once the resize channel is able to
accept, only the most-recent event will be written. Previously we'd
have written one resize event for every received signal, even if the
resize consumer was falling behind.

The initial resize command sent to the terminal window over the resize
channel may never be delivered in case of error.
Hence it is necessary to consume all data from the resize channel to
avoid a deadlock on startup.

We were closing resize both on the receiver and the sender side.
This was racy as the sender might have written to a closed channel.
If the container could not be created, the attach exited
immediately causing the channel to be closed before the write from
resizeTty.
Change the logic to close only from the senderSide and add another
channel to notify the resizeTty goroutine when the container exited.
