cmd/podman/common/completion.go: fix FIXMEs
There is no good way to recommend labels for podman container runlabel.

Add the missing max-size log option. These are the only documented
options so the completion should not suggest something different.

Add proper --stop-signal completion. It will now complete all supported
signal names both upper and lowercase depending on the user input. Also
it work with and without the SIG prefix.

Fixing the TODOs in this file are more complicated since they describe
bigger features.

shell completion --format: add help to function with args
From a template users POV it is not importent when they use a struct field or
method. They only notice the difference when the function requires arguments.
So lets be nice and let the user know that this method requires arguments
via the help text.

This is how it now looks like when the completion descriptions are enabled
on bash:
```
$  bin/podman ps --format {{.Created.A
{{.Created.AddDate       (This is a function and requires 3 arguments)   {{.Created.After         (This is a function and requires 1 argument)
{{.Created.Add           (This is a function and requires 1 argument)    {{.Created.AppendFormat   (This is a function and requires 2 arguments)

shell completion --format: support maps and functions
Currently we only support structs in a template string like this:
`{{.var1.test.` -> this meams that test must be a struct field on var1.

Now with this var1 and test could also be either a map or function which
returns a struct.

A actual example:
`podman container inspect  --format {{.NetworkSettings.Networks.netname.`
Now we can complete the struct fileds after netname. Note that this
cannot complete map keys since they are empty by default, so it is
impossible to get them in the completion logic.

Also this fixes a panic with embeeded nil structs

shell completion --format: fix embedded struct handling
When a struct is embeeded it is possible that we end up with same names
but different types, this results in incorrect completions. The go
template logic always preferes the actual field/method name before the
one from the embedded one. Thefore the completion logic should do the
same. First get all method/fields names from the struct and then only
add the field names from the embedded struct when they are not already
present in the list.

Valentin Rothberg 4eff0c8cf2 pod: add exit policies
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".

shell completion --format: work with nil structs
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.

enable gocritic linter
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.

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

when getting healthcheck values from an image, if the image does not

when inspecting a container with a healthcheck command, a customer
