Previously, we always computed pause path from the Rootless
runtime directory. Problem: this does not match the behavior of
Libpod when the directory changes. Libpod will continue to use
the previous directory, cached in the database; Pause pidfiles
will swap to the new path. This is problematic when the directory
needs to exist to write the pidfile, and Libpod is what creates
the directory.
There are two potential solutions - allow the pause pidfile to
move and just make the directory when we want to write it, or use
the cached Libpod paths for a guaranteed location. This patch
does the second, because it seems safer - we will never miss a
previously-existing pidfile because the location is now
consistent.

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.

Instead of being interpreted as an argument to the boolean flag,
the 'true' is being intepreted as the Podman command to be run -
so we're trying to run `podman true`, which does not exist. This
causes the cleanup command to fail when `--log-level=debug` is
set, so containers are not cleaned up or removed.
This problem is easily reproduced with any command combining the
`--rm`, `-d`, and `--log-level=debug` flags - the command will
execute and exit, but the container will not be removed.
Separate, but worth looking into later: the errors we get on
trying `podman true` with any flags are terrible - if you just
type `podman true` you get a quite sane "Unrecognized command"
error, but if you try `podman true --rm` you get an "unknown flag
--rm" error - which makes very little sense given the command
itself doesn't exist.

The It("podman wait to pause|unpause condition"... test is
flaking every so often when a messages is sent in the second
function to a channel. It is my believe that in between the time
the first function sends a message to the channel and before it closes
the channel the second errChan=make() has happened. This would mean that
the fist function closes the second errChan, and then when the second
function sends a message to the second errChan, it fails and blows up with
the error you are seeing.
By creating a different variable for the second channel, we eliminate the race.

The goal is to improve errors when users use the wrong transport
in certain cases we stutter, in other cases we don't give enough
information.
Remove stutters when failing to pull remote images, because of
lack of support.
Fix errors returned by reference.Parse to wrap in image that was being
checked.

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.

The volume src path should not be validated in specgen since
the remote client also uses that part and the path must only
exists on the server. This now fails later and only on the
server and not the client.
I don't think I can add a test for this because the CI runs
server and client always on the same vm.

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.

In the current code we were translating the created time
from a time.Time to a unix epoch, this was leading to a loss
of precession, and some unexpected results where the sorting
order of containers was misordered because of the precession loss.
If we pass around created as time.Time, we do not loose the precission.
