Add shell completion for paths inside the container or image. Currently
podman run IMAGE [TAB] only uses the default shell completion which
suggests paths on the host. This is fine for some cases but often the
user wants a path which only exists in the image/container.
This commits adds support for that. Both podman create/run can now
complete the paths from the image, podman cp ctr:... now completes paths
from the actual container.

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.

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)

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
Fixes#14223
Signed-off-by: Paul Holzinger <pholzing@redhat.com>
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.

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".

We should not include the anonymous twice in the suggestions.

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

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.

Make use of the new network interface in libpod.
This commit contains several breaking changes:
- podman network create only outputs the new network name and not file
path.
- podman network ls shows the network driver instead of the cni version
and plugins.
- podman network inspect outputs the new network struct and not the cni
conflist.
- The bindings and libpod api endpoints have been changed to use the new
network structure.
The container network status is stored in a new field in the state. The
status should be received with the new `c.getNetworkStatus`. This will
migrate the old status to the new format. Therefore old containers should
contine to work correctly in all cases even when network connect/
disconnect is used.
New features:
- podman network reload keeps the ip and mac for more than one network.
- podman container restore keeps the ip and mac for more than one
network.
- The network create compat endpoint can now use more than one ipam
config.

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.

Implement a new network interface to abstract CNI from libpod. The
interface is implemented for the CNI backend but in the future we can
add more backends.
The code is structured in three new packages:
- `libpod/network/types`: contains the interface definition
and the necessary types for it.
- `libpod/network/cni` contains the interface implementation for the CNI
backend.
- `libpod/network/util` a set of utility functions related to
networking.
The CNI package uses ginkgo style unit tests. To test Setup/Teardown the
test must be run as root. Each test will run in their own namespace to
make the test independent from the host environment.
New features with the CNI backend:
- The default network will be created in memory if it does not exists on
disk.
- It can set more than one static IP per container network.
- Networks are loaded once from disk and only if this interface is
used, e.g. for commands such as `podman info` networks are not loaded.
This reduces unnecessary disk IO.
This commit only adds the interface it is not wired into libpod. This
requires a lot of breaking changes which will be done in a followup
commit.
Once this is integrated into libpod the current network code under
`libpod/network` should be removed. Also the dependency on OCICNI
should be dropped.
