The network ID is not stored. It is just the sha256 hash from
the network name. There is a risk of a potential hash collision.
However it's very unlikely and even if we hit this it will
complain that more than network with this ID exists.
The main benefit is that the compat api can have proper
network ID support. Also this adds the support for
`podman network ls --format "{{.ID}}"` and `--filter id=<ID>`.
It also ensures that we can do network rm <ID> and network
inspect <ID>.
Since we use a hash this commit is backwards compatible even for
already existing networks.

As described in issue #8507 this commit contains a breaking
change which is not wanted in v2.2.

Add label support for podman network create. Use the `args`
field in the cni config file to store the podman labels.
Use `podman_labels` as key name and store the labels as
map[string]string.
For reference: https://github.com/containernetworking/cni/blob/master/CONVENTIONS.md#args-in-network-confighttps://github.com/containernetworking/cni/blob/spec-v0.4.0/SPEC.md#network-configuration
Example snippet:
```
...
"args": {
"podman_labels": {
"key1":"value1",
"key2":"value2"
}
}
...
```
Make podman network list support several filters. Supported filters are name,
plugin, driver and label. Filters with different keys work exclusive. Several label
filters work exclusive and the other filter keys are working inclusive.
Also adjust the compat api to support labels in network create and list.
Breaking changes:
- podman network ls -f shortform is used for --filter instead --format
This matches docker and other podman commands (container ps, volume ps)
- libpod network list endpoint filter parameter is removed. Instead the
filters paramter should be used as json encoded map[string][]string.

In k8s a persistent volume claim (PVC) allow pods to define a volume
by referencing the name of a PVC. The PVC basically contains criterias
that k8s then use to select which storage source it will use for the
volume.
Podman only provide one abtracted storage, the named volumes, and
create them if they don't exists yet. So this patch simply use a
volume with the name of the PVC.

Replace the simple map of names to paths with a map of names to a struct
to allow passing more parameters. Also move the code to parse the volumes
to its own file to avoid making the playKubePod() function overly complex.
Finally rework the kube volumes test to also be ready to support more
volume types.

First, make sure we are only trying to remove the network
interface if we are root.
Second, if we cannot get the interface name (e.g macvlan config)
then we should not fail. Just remove the config file.

For docker compatibility we need to support --platform
flag.
podman create --platform
podman run --platform
podman pull --platform
Since we have --override-os and --override-arch already
this can be done just by modifying the client to split
the --platform call into os and arch and then pass those
options to the server side.

We allow a container to be connected to several cni networks
but only if they are listed comma sperated. This is not intuitive
for users especially since the flag parsing allows multiple string
flags but only would take the last value. see: spf13/pflag#72
Also get rid of the extra parsing logic for pods. The invalid options
are already handled by `pkg/specgen`.
A test is added to prevent a future regression.

this enables the ability to connect and disconnect a container from a
given network. it is only for the compatibility layer. some code had to
be refactored to avoid circular imports.
additionally, tests are being deferred temporarily due to some
incompatibility/bug in either docker-py or our stack.

All of our filters worked exclusive resulting in `--filter status=created --filter status=exited` to return nothing.
In docker filters with the same key work inclusive with the only exception being `label` which is exclusive. Filters with different keys always work exclusive.

Having play kube start the pod is not always appropriate, one might
for example like to have the pod running as a set of systemd services.
Add a `start` option to the command line and API to control if the pod
should be started or not; it defaults to true for backward
compatibility.

Remove references on contrib/gate. The gating image is currently not

in Quay once the change is merged.
Note that running `make validate` in a container is still desired.
