Add auto-update support to `podman kube play`. Auto-update policies can
be configured for:
* the entire pod via the `io.containers.autoupdate` annotation
* a specific container via the `io.containers.autoupdate/$name` annotation
To make use of rollbacks, the `io.containers.sdnotify` policy should be
set to `container` such that the workload running _inside_ the container
can send the READY message via the NOTIFY_SOCKET once ready. For
further details on auto updates and rollbacks, please refer to the
specific article [1].
Since auto updates and rollbacks bases on Podman's systemd integration,
the k8s YAML must be executed in the `podman-kube@` systemd template.
For further details on how to run k8s YAML in systemd via Podman, please
refer to the specific article [2].
An examplary k8s YAML may look as follows:
```YAML
apiVersion: v1
kind: Pod
metadata:
annotations:
io.containers.autoupdate: "local"
io.containers.autoupdate/b: "registry"
labels:
app: test
name: test_pod
spec:
containers:
- command:
- top
image: alpine
name: a
- command:
- top
image: alpine
name: b

When a kube yaml has a volume set as empty dir, podman

attach it to the containers running in the pod. When the pod
is removed, the empy dir volume created is also removed.

Kubernetes secrets have a different structure than podman and therefore have to be handeled differently.

Previously, if a container had healthchecks disabled in the
docker-compose.yml file and the user did a `podman inspect <container>`,
they would have an incorrect output:
```
"Healthcheck":{
"Test":[
"CMD-SHELL",
"NONE"
],
"Interval":30000000000,
"Timeout":30000000000,
"Retries":3
}
```
After a quick change, the correct output is now the result:
```
"Healthcheck":{
"Test":[
"NONE"
]
}
```
Additionally, I extracted the hard-coded strings that were used for
comparisons into constants in `libpod/define` to prevent a similar issue
from recurring.

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 using play kube and generate kube, we need to support if bind
mounts have selinux options. As kubernetes does not support selinux in
this way, we tuck the selinux values into a pod annotation for
generation of the kube yaml. Then on play, we check annotations to see
if a value for the mount exists and apply it.

Kubernetes has a concept of init containers that run and exit before
the regular containers in a pod are started. We added init containers
to podman pods as well. This patch adds support for generating init
containers in the kube yaml when a pod we are converting had init
containers. When playing a kube yaml, it detects an init container
and creates such a container in podman accordingly.
Note, only init containers created with the init type set to "always"
will be generated as the "once" option deletes the init container after
it has run and exited. Play kube will always creates init containers
with the "always" init container type.

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.
