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)

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.

Add support for simple rollbacks during `podman auto-update`. Rollbacks
are enabled by default. If a systemd unit cannot be restarted after an
update, the previous image will be retagged and the unit will be
restarted a second time.
Add system tests for rollbacks. Also fix a bug in the restart sequence;
we have to use the channel to actually know whether the restart was
successful or not.
NOTE: To make rollbacks really useful, users must run their containers
with `--sdnotify=container` such that the containers send the ready
message over the (mounted) socket. This way, restarting the systemd
units during auto update will block until the message has been received
(or a timeout kicked in).

this is the first pass at implementing init containers for podman pods.
init containersare made popular by k8s as a way to run setup for pods
before the pods standard containers run.
unlike k8s, we support two styles of init containers: always and
oneshot. always means the container stays in the pod and starts
whenever a pod is started. this does not apply to pods restarting.
oneshot means the container runs onetime when the pod starts and then is
removed.
