8fac34b8ff Pod Device Support
added support for pod devices. The device gets added to the infra container and
recreated in all containers that join the pod.

This required a new container config item to keep track of the original device passed in by the user before
the path was parsed into the container device.

d28e85741f InfraContainer Rework
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)

c0b1edd6a4 Network interface
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.

221b1add74 Add support for pod inside of user namespace.
Add the --userns flag to podman pod create and keep
track of the userns setting that pod was created with
so that all containers created within the pod will inherit
that userns setting.

Specifically we need to be able to launch a pod with
--userns=keep-id

f7321681d0 podman pod create --pid flag
added support for --pid flag. User can specify ns:file, pod, private, or host.
container returns an error since you cannot point the ns of the pods infra container

bbd085ad1e Podman Pod Create --cpus and --cpuset-cpus flags
Added logic and handling for two new Podman pod create Flags.

--cpus specifies the total number of cores on which the pod can execute, this
is a combination of the period and quota for the CPU.

 --cpuset-cpus is a string value which determines of these available cores,
how many we will truly execute on.

c4627b5846 Fix container and pod create commands for remote create
In `podman inspect` output for containers and pods, we include
the command that was used to create the container. This is also
used by `podman generate systemd --new` to generate unit files.

With remote podman, the generated create commands were incorrect
since we sourced directly from os.Args on the server side, which
was guaranteed to be `podman system service` (or some variant
thereof). The solution is to pass the command along in the
Specgen or PodSpecgen, where we can source it from the client's
os.Args.

This will still be VERY iffy for mixed local/remote use (doing a
`podman --remote run ...` on a remote client then a
`podman generate systemd --new` on the server on the same
container will not work, because the `--remote` flag will slip
in) but at the very least the output of `podman inspect` will be
correct. We can look into properly handling `--remote` (parsing
it out would be a little iffy) in a future PR.

402c68b41d pod create: add --infra-conmon-pidfile
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.

2d68dc776d Fix parsing of --network for podman pod create

rootless `podman pod create` to fail. Also, we were missing the
`--net` alias for `--network`, so add that.

7ac3d906b5 Rework port parsing to support --expose and -P
As part of this, make a major change to the type we use to
represent port mappings in SpecGen (from using existing OCICNI
structs to using our own custom one). This struct has the
advantage of supporting ranges, massively reducing traffic over
the wire for Podman commands using them (for example, the
`podman run -p 5000-6000` command will now send only one struct
instead of 1000). This struct also allows us to easily validate
which ports are in use, and which are not, which is necessary for
--expose.

Once we have parsed the ports from the new struct, we can produce
an accurate map including all currently requested ports, and use
that to determine what ports need to be exposed (some requested
exposed ports may already be included in a mapping from --publish
and will be ignored) and what open ports on the host we can map
them to.
