network create: add --interface-name
Allow users to customize the network_interface option is the network
config. For bridge this allows users to change the bridge name and for
maclvan it will be the same as `--opt parent=...`.
However the main reason for this option is to allow netavark plugins to
make use of it. I demoed the host-device plugin which makes use of this
as an example. While we could let users set them via --opt it is more
natural to just use the field which is designed for that purpose.

network create: allow multiple subnets
podman network create --subnet, --gateway and --ip-range can now be
specified multiple times to join the network to more than one subnet.
This is very useful if you want to use a dual stack network and assign a
fixed ipv4 and ipv6 subnet. The order of the options is important here,
the first --gateway/--ip-range will be assigned to the first subnet and
so on.

Wire network interface into libpod
Make use of the new network interface in libpod.

This commit contains several breaking changes:
- podman network create only outputs the new network name and not file
  path.
- podman network ls shows the network driver instead of the cni version
  and plugins.
- podman network inspect outputs the new network struct and not the cni
  conflist.
- The bindings and libpod api endpoints have been changed to use the new
  network structure.

The container network status is stored in a new field in the state. The
status should be received with the new `c.getNetworkStatus`. This will
migrate the old status to the new format. Therefore old containers should
contine to work correctly in all cases even when network connect/
disconnect is used.

New features:
- podman network reload keeps the ip and mac for more than one network.
- podman container restore keeps the ip and mac for more than one
  network.
- The network create compat endpoint can now use more than one ipam
  config.

The man pages and the swagger doc are updated to reflect the latest
changes.

Jhon Honce 33944cefe7 [Techinal Debt] Cleanup ABI vs. Tunnel CLI commands
[NO TESTS NEEDED]

This commit cleans up two issues:
* Most commands support all EngineModes so default to that. Let
  outlayers declare their intent.
* Use cobra.Annotations to set supported EngineMode. This simplies
  instantiating commands as there is now one method to communicate a
  commands requirements rather than two.
* Combined aliased commands into one file
* Fixed aliased commands where Args field did not match
* Updated examples in README.md for writing commands
* Remove redundant flag DisableFlagsInUseLine in cobra.Command

Paul Holzinger 2870a0b0a6 Add system test for shell completion
There exists a unit test to ensure that shell completion functions are
defined. However there was no check about the quality of the provided
shell completions. Lets change that.

The idea is to create a general test that makes sure we are suggesting
containers,pods,images... for the correct commands. This works by
reading the command use line and checking for each arg if we provide
the correct suggestions for this arg.

It includes the following tests:
- flag suggestions if [options] is set
- container, pod, image, network, volume, registry completion
- path completion for the appropriate arg KEYWORDS (`PATH`,`CONTEXT`,etc.)
- no completion if there are no args
- completion for more than one arg if it ends with `...]`

The test does not cover completion values for flags and not every arg KEYWORD
is supported. This is still a huge improvement and covers most use cases.

This test spotted several inconsistencies between the completion and the
command use line. All of them have been adjusted to make the test pass.

The biggest advantage is that the completions always match the latest
command changes. So if someone changes the arguments for a command this
ensures that the completions must be adjusted.

Paul Holzinger 8494bcb866 podman network label support
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-config
https://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.

Paul Holzinger b5d1d89a37 Add shell completion with cobra
Allow automatic generation for shell completion scripts
with the internal cobra functions (requires v1.0.0+).

This should replace the handwritten completion scripts
and even adds support for fish. With this approach it is
less likley that completions and code are out of sync.

We can now create the scripts with
- podman completion bash
- podman completion zsh
- podman completion fish

To test the completion run:
source <(podman completion bash)

The same works for podman-remote and podman --remote and
it will complete your remote containers/images with
the correct endpoints values from --url/--connection.

The completion logic is written in go and provided by the
cobra library. The completion functions lives in
`cmd/podman/completion/completion.go`.

The unit test at cmd/podman/shell_completion_test.go checks
if each command and flag has an autocompletion function set.
This prevents that commands and flags have no shell completion set.

This commit does not replace the current autocompletion scripts.

baude fe3faa517e prevent unpredictable results with network create|remove
due to a lack of "locking" on cni operations, we could get ourselves in trouble when doing rapid creation or removal of networks.  added a simple file lock to deal with the collision and because it is not considered a performent path, use of the file lock should be ok.  if proven otherwise in the future, some generic shared memory lock should be implemented for libpod and also used here.

moved pkog/network to libpod/network because libpod is now being pulled into the package and it has therefore lost its generic nature. this will make it easier to absorb into libpod as we try to make the network closer to core operations.

Valentin Rothberg 8489dc4345 move go module to v2
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].

Ed Santiago 6864a5547a BATS tests: new too-many-arguments test
...plus a few others. And fixes to actual parsing.

If a command's usage message includes '...' in the
argument list, assume it can take unlimited arguments.
Nothing we can check.

For all others, though, the ALL-CAPS part on the
right-hand side of the usage message will define
an upper bound on the number of arguments accepted
by the command. So in our 'podman --help' test,
generate N+1 args and run that command. We expect
a 125 exit status and a suitably helpful error message.

Not all podman commands or subcommands were checking,
so I fixed that. And, fixed some broken usage messages
(all-caps FLAGS, and '[flags]' at the end of 'ARGS').
Add new checks to the help test to prevent those in
the future.

Plus a little refactoring/cleanup where necessary.
