add the ability for users to specify more than one container at a time
while using podman logs. If more than one container is being displayed,
podman will also prepend a shortened container id of the container on
the log line.
also, enabled the podman-remote logs command during the refactoring of
the above ability.

Make the usage messages (and options) different between
podman inspect, podman image inspect, and podman container inspect.
Disable inapplicable options (-l, -s) for podman image inspect
Disable -t (type) when the type is implicit through the subcommand.
Update man page to reflect differences in usage.
Fix broken test.
Uglier than desirable due to Go and Cobra limitations

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`
Try 'podman container --help' for more information.

The current aliased commands

Do not work properly. The global storage options are broken.
This patch fixes this issue.

project is more well maintained. There are also some technical reasons
as well which extend into our remote client work.

users to verify the existence of a container or image by ID or name. The return
code can be 0 (success), 1 (failed to find), or 125 (failed to work with runtime).

runc uses CRIU to support checkpoint and restore of containers. This
brings an initial checkpoint/restore implementation to podman.
None of the additional runc flags are yet supported and container
migration optimization (pre-copy/post-copy) is also left for the future.
The current status is that it is possible to checkpoint and restore a
container. I am testing on RHEL-7.x and as the combination of RHEL-7 and
CRIU has seccomp troubles I have to create the container without
seccomp.
With the following steps I am able to checkpoint and restore a
container:
# podman run --security-opt="seccomp=unconfined" -d registry.fedoraproject.org/f27/httpd
# curl -I 10.22.0.78:8080
HTTP/1.1 403 Forbidden # <-- this is actually a good answer
# podman container checkpoint <container>
# curl -I 10.22.0.78:8080
curl: (7) Failed connect to 10.22.0.78:8080; No route to host
# podman container restore <container>
# curl -I 10.22.0.78:8080
HTTP/1.1 403 Forbidden
I am using CRIU, runc and conmon from git. All required changes for
checkpoint/restore support in podman have been merged in the
corresponding projects.
To have the same IP address in the restored container as before
checkpointing, CNI is told which IP address to use.
If the saved network configuration cannot be found during restore, the
container is restored with a new IP address.
For CRIU to restore established TCP connections the IP address of the
network namespace used for restore needs to be the same. For TCP
connections in the listening state the IP address can change.
During restore only one network interface with one IP address is handled
correctly. Support to restore containers with more advanced network
configuration will be implemented later.
v2:
* comment typo
* print debug messages during cleanup of restore files
* use createContainer() instead of createOCIContainer()
* introduce helper CheckpointPath()
* do not try to restore a container that is paused
* use existing helper functions for cleanup
* restructure code flow for better readability
* do not try to restore if checkpoint/inventory.img is missing
* git add checkpoint.go restore.go
v3:
* move checkpoint/restore under 'podman container'
v4:
* incorporated changes from latest reviews

Execute the command as described by a container image. The value of the label is processed
into a command by:
1. Ensuring the first argument of the command is podman.
2. Substituting any variables with those defined by the environment or otherwise.
If no label exists in the container image, nothing is done.
podman container runlabel LABEL IMAGE extra_args

Don't print potentially verbose help messages in case of usage errors,
but print only the usage error followed by a pointer to the command's
help. This aligns with Docker.
```
$ podman run -h
flag needs an argument: -h
See 'podman run --help'.

When we run containers in detach mode, nothing cleans up the network stack or
the mount points. This patch will tell conmon to execute the cleanup code when
the container exits.
It can also be called to attempt to cleanup previously running containers.
