We missed bumping the go module, so let's do it now :)
* Automated go code with github.com/sirkon/go-imports-rename
* Manually via `vgrep podman/v2` the rest

when creating a pod with --infra-image and using a untagged image for
the infra-image (none/none), the lookup for the image's name was
creating a panic.

We need an extra field in the pod infra container config. We may
want to reevaluate that struct at some point, as storing network
modes as bools will rapidly become unsustainable, but that's a
discussion for another time. Otherwise, straightforward plumbing.

Ensure that infra containers for pods will grab default sysctls
from containers.conf, to match how other containers are created.
This mostly affects the other containers in the pod, which will
inherit those sysctls when they join the pod's namespaces.

It looks like this was previously removed because the default
hard-coded `/pause` so we would never take into account the image
config. I've removed the default in c/common and re-added support
to check config files.
While we're at it, fix ENTRYPOINT support - we should not be
setting this if we got ENTRYPOINT from the image.

Containers that share IPC Namespaces share each others
/dev/shm, which means a private /dev/shm needs to be setup
for the infra container.
Added a system test and an e2e test to make sure the
/dev/shm is shared.

Most Libpod containers are made via `pkg/specgen/generate` which
includes code to generate an appropriate exit command which will
handle unmounting the container's storage, cleaning up the
container's network, etc. There is one notable exception: pod
infra containers, which are made entirely within Libpod and do
not touch pkg/specgen. As such, no cleanup process, network never
cleaned up, bad things can happen.
There is good news, though - it's not that difficult to add this,
and it's done in this PR. Generally speaking, we don't allow
passing options directly to the infra container at create time,
but we do (optionally) proxy a pre-approved set of options into
it when we create it. Add ExitCommand to these options, and set
it at time of pod creation using the same code we use to generate
exit commands for normal containers.

With the advent of Podman 2.0.0 we crossed the magical barrier of go
modules. While we were able to continue importing all packages inside
of the project, the project could not be vendored anymore from the
outside.
Move the go module to new major version and change all imports to
`github.com/containers/libpod/v2`. The renaming of the imports
was done via `gomove` [1].

Add an `--infra-conmon-pidfile` flag to `podman-pod-create` to write the
infra container's conmon process ID to a specified path. Several
container sub-commands already support `--conmon-pidfile` which is
especially helpful to allow for systemd to access and track the conmon
processes. This allows for easily tracking the conmon process of a
pod's infra container.

Add support to auto-update containers running in systemd units as
generated with `podman generate systemd --new`.
`podman auto-update` looks up containers with a specified
"io.containers.autoupdate" label (i.e., the auto-update policy).
If the label is present and set to "image", Podman reaches out to the
corresponding registry to check if the image has been updated. We
consider an image to be updated if the digest in the local storage is
different than the one of the remote image. If an image must be
updated, Podman pulls it down and restarts the container. Note that the
restarting sequence relies on systemd.
At container-creation time, Podman looks up the "PODMAN_SYSTEMD_UNIT"
environment variables and stores it verbatim in the container's label.
This variable is now set by all systemd units generated by
`podman-generate-systemd` and is set to `%n` (i.e., the name of systemd
unit starting the container). This data is then being used in the
auto-update sequence to instruct systemd (via DBUS) to restart the unit
and hence to restart the container.
Note that this implementation of auto-updates relies on systemd and
requires a fully-qualified image reference to be used to create the
container. This enforcement is necessary to know which image to
actually check and pull. If we used an image ID, we would not know
which image to check/pull anymore.

Before Libpod supported named volumes, we approximated image
volumes by bind-mounting in per-container temporary directories.
This was handled by Libpod, and had a corresponding database
entry to enable/disable it.
However, when we enabled named volumes, we completely rewrote the
old implementation; none of the old bind mount implementation
still exists, save one flag in the database. With nothing
remaining to use it, it has no further purpose.

This adds network-related options to the pod in the database. We
are going to add the CLI frontend in further patches.
In short, this should greatly improve the ability of pods to
configure networking, once the CLI parsing is added.

In order to run Podman with VM-based runtimes unprivileged, the
network must be set up prior to the container creation. Therefore
this commit modifies Podman to run rootless containers by:
1. create a network namespace
2. pass the netns persistent mount path to the slirp4netns
to create the tap inferface
3. pass the netns path to the OCI spec, so the runtime can
enter the netns

`always`: podman will always pull the image.

the compilation demands of having libpod in main is a burden for the
remote client compilations. to combat this, we should move the use of
libpod structs, vars, constants, and functions into the adapter code
where it will only be compiled by the local client.
this should result in cleaner code organization and smaller binaries. it
should also help if we ever need to compile the remote client on
non-Linux operating systems natively (not cross-compiled).

When sourcing from an image, we need to grab its entrypoint first
and then add command on to mimic the behavior of Docker.
The default Kube pause image just sets ENTRYPOINT, and not CMD,
so nothing changes there, but this ought to fix other images
(for example, nginx would try to run the pause command instead of
an nginx process without this patch)
