bd9987239d Scrub podman commands to use report package
Refactor podman commands that have drifted from using
c/common report pkg. Report pkg is needed to implement
go template functions.

Removed obsolete code from podman which exists in c/common.

Latest template library added default newlines and method to
remove them. Incorporated needed changes in c/common PR below.

Depends on https://github.com/containers/common/pull/624
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1855983

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
  initialization.

d81021ed26 Add go template shell completion for --format
The --format flags accepts go template strings. I use this often but I
consistently forget the field names. This commit adds a way to provide
shell completion for the --format flag. It works by automatically
receiving the field names with the reflect package from the given
struct. This requires almost no maintenance since this ensures that we
always use the correct field names. This also works for nested structs.

```
$ podman ps --format "{{.P"
{{.Pid}}      {{.PIDNS}}    {{.Pod}}      {{.PodName}}  {{.Ports}}
```

NOTE: This only works when you use quotes otherwise the shell does not
provide completions. Also this does not work for fish at the moment.

a6af56f5b4 Add 'MemUsageBytes' format option
Although storage is more human-readable when expressed in SI units,
IEC/JEDEC (Bytes) units are more pertinent for memory-related values
(and match the format of the --memory* command-line options).

(To prevent possible compatibility issues, the default SI display is
left unchanged)

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.

Closes #6440

19b955f099 stats: break out CLI options
Have a clear separation of concerns for the CLI-only options (and their
logic) from the backend.  The backend logic is now easier to understand

376ba349bf stats refactor
Refactor the entities' stats API to simplify using it and reduce the
risk of running into concurrency issues at the call sites.  Further
simplify the stats code by de-spaghetti-ing the logic and reducing
duplicate code.

`ContainerStats` now returns a data channel and an error.  If the error
is nil, callers can read from the channel.

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].

3cef598fc2 container stats: fix --no-stream race
Fix a race in `podman container stats` by waiting for the client to
consume the data in the channel.  This requires a `sync.WaitGroup` (or
semaphore) in the client and to also close the channel the backend.
