I am constantly attempting to add the podname to the last
argument to podman pod create. Allowing this makes it match
podman volume create and podman network create.
It does not match podman container create, since podman container create
arguments specify the arguments to run with the container.
Still need to support the --name option for backwards compatibility.

- Look for and prevent lower-case arg descriptions:
podman cmd [arg]
- Look for and prevent optional-mandatory misordering:
podman cmd [ARG] ARG
- Tighter whitespace checks (and fix podman pod ps)
- simplify a no-longer-necessary mess! #8635 fixed the
horrible "CONTAINER | IMAGE" strings (with spaces),
so there's no longer a need to special-case those.
The one-extra-arg check is now much cleaner.
Minor refactoring.

Add the notion of an "exit policy" to a pod. This policy controls the
behaviour when the last container of pod exits. Initially, there are
two policies:
- "continue" : the pod continues running. This is the default policy
when creating a pod.
- "stop" : stop the pod when the last container exits. This is the
default behaviour for `play kube`.
In order to implement the deferred stop of a pod, add a worker queue to
the libpod runtime. The queue will pick up work items and in this case
helps resolve dead locks that would otherwise occur if we attempted to
stop a pod during container cleanup.
Note that the default restart policy of `play kube` is "Always". Hence,
in order to really solve #13464, the YAML files must set a custom
restart policy; the tests use "OnFailure".

For the AutocompleteFormat function we expect the correct template
struct which is used in the golang template. The function can handle
both struct and pointer to a struct. Using the reference is more
efficient since it doe snot have to copy the whole struct.
Also change some structs to use he actual type from the template instead
of some nested one to make sure it has to correct fields.
Signed-off-by: Paul Holzinger <pholzing@redhat.com>
AutocompleteFormat() takes the format struct as argument. Often the structs
are deeply nested and contain other structs. Up until now if there was a
pointer to a struct the logic was not able to get the field names from
that, simply because the pointer was nil. However it is possible to
create a new initialized type with reflect.New(). This allows us to
complete all struct fields/functions even when there nil pointers.
Therefore we can drop the extra initialization which was done by some
callers.

The linter ensures a common code style.
- use switch/case instead of else if
- use if instead of switch/case for single case statement
- add space between comment and text
- detect the use of defer with os.Exit()
- use short form var += "..." instead of var = var + "..."
- detect problems with append()
```
newSlice := append(orgSlice, val)
```
This could lead to nasty bugs because the orgSlice will be changed in
place if it has enough capacity too hold the new elements. Thus we
newSlice might not be a copy.
Of course most of the changes are just cosmetic and do not cause any
logic errors but I think it is a good idea to enforce a common style.
This should help maintainability.

When podman gets an error it prints out "Error: " before

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

Rework the --network parse logic to support multiple networks with
specific network configuration settings.
--network can now be set multiple times. For bridge network mode the
following options have been added:
- **alias=name**: Add network-scoped alias for the container.
- **ip=IPv4**: Specify a static ipv4 address for this container.
- **ip=IPv6**: Specify a static ipv6 address for this container.
- **mac=MAC**: Specify a static mac address address for this container.
- **interface_name**: Specify a name for the created network interface inside the container.
So now you can set --network bridge:ip=10.88.0.10,mac=44:33:22:11:00:99
for the default bridge network as well as for network names.
This is better than using --ip because we can set the ip per network
without any confusion which network the ip address should be assigned
to.
The --ip, --mac-address and --network-alias options are still supported
but --ip or --mac-address can only be set when only one network is set.
This limitation already existed previously.
The ability to specify a custom network interface name is new

In commit d81021ed26 I introduced shell completion for the `--format`
flag. This is a very nice way to complete go template field names.
However it did not work correct for anonymous fields. In this case the
child fields can be accessed directly from the parent.
For example:
```
type Anonymous struct {
Field1 string
Field2 string
...
}
type MyType struct {
Anonymous
}
var s = MyType{}
```
Now if you want to access a field from the Anonymous struct you can just
do `s.Field1`. The same is allowed for go templates, using `{{.Field1}}`
should work. This commit adds this functionality, if the field is anonymous
read the child field names recursively and add them to the suggestions.

InfraContainer should go through the same creation process as regular containers. This change was from the cmd level
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)

The --format flags accepts go template strings. I use this often but I
consistently forget the field names. This commit adds a way to provide
shell completion for the --format flag. It works by automatically
receiving the field names with the reflect package from the given
struct. This requires almost no maintenance since this ensures that we
always use the correct field names. This also works for nested structs.
```
$ podman ps --format "{{.P"
{{.Pid}} {{.PIDNS}} {{.Pod}} {{.PodName}} {{.Ports}}
```
NOTE: This only works when you use quotes otherwise the shell does not
provide completions. Also this does not work for fish at the moment.
