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.

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.

The ListContainers API previously had a Pod parameter, which
determined if pod name was returned (but, notably, not Pod ID,
which was returned unconditionally). This was fairly confusing,
so we decided to deprecate/remove the parameter and return it
unconditionally.
To do this without serious performance implications, we need to
avoid expensive JSON decodes of pod configuration in the DB. The
way our Bolt tables are structured, retrieving name given ID is
actually quite cheap, but we did not expose this via the Libpod
API. Add a new GetName API to do this.

This patch fixes connection counters for v2 endpoints

Signed-off-by: Sami Korhonen <skorhone@gmail.com>
StateHijacked is a terminal state. If hijacked connection
is registered as an active connection, connection will
never be unregistered. This causes two issues
First issue is that active connection counters are off.
Second issue is a resource leak caused by connection
object that is stored to a map.
After this patch hijacked connections are no longer
visible in counters. If a counter for hijacked
connections is required, podman must track
connections returned by Hijacker.Hijack()
It might make sense to develop abstraction layer for
hijacking - and move all hijacking related code to a
separate package. Hijacking code is prone to resource
leaks and it should be thoroughly tested.

The biggest obstacle here was cleanup - we needed a way to remove
detached exec sessions after they exited, but there's no way to
tell if an exec session will be attached or detached when it's
created, and that's when we must add the exit command that would
do the removal. The solution was adding a delay to the exit
command (5 minutes), which gives sufficient time for attached
exec sessions to retrieve the exit code of the session after it
exits, but still guarantees that they will be removed, even for
detached sessions. This requires Conmon 2.0.17, which has the new
`--exit-delay` flag.
As part of the exit command rework, we can drop the hack we were
using to clean up exec sessions (remove them as part of inspect).
This is a lot cleaner, and I'm a lot happier about it.
Otherwise, this is just plumbing - we need a bindings call for
detached exec, and that needed to be added to the tunnel mode
backend for entities.

This adds bindings for starting exec sessions, and then uses them

* Add a hidden `--registries-conf` flag. Buildah exposes the same

* Move `podman system service` logic into `cmd` to prevent circular
