Valentin Rothberg 762b787fbf new endpoint: /libpod/containers/stats
Add a new endpoint for container stats allowing for batch operations on
more than one container.  The new endpoint deprecates the
single-container endpoint which will eventually be removed with the next
major release.

Matthew Heon 569854d634 Unconditionally retrieve pod names via API
The ListContainers API previously had a Pod parameter, which
determined if pod name was returned (but, notably, not Pod ID,
which was returned unconditionally). This was fairly confusing,
so we decided to deprecate/remove the parameter and return it
unconditionally.

To do this without serious performance implications, we need to
avoid expensive JSON decodes of pod configuration in the DB. The
way our Bolt tables are structured, retrieving name given ID is
actually quite cheap, but we did not expose this via the Libpod
API. Add a new GetName API to do this.

Fixes #7214

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].

New script cross-references r.Handle() and r.HandleFunc()

and exits failure (with descriptive error messages) if any
comments do not match the code.

This script should not be necessary: the swagger comments

Ed Santiago 2a411bcbfa Swagger: fix inconsistencies (try #2)
As I've mentioned once or twice, hand-maintained swagger docs
are evil. This commit attempts to fix:

  * Inconsistent methods (swagger says POST but code signature
    says GET)

  * Inconsistent capitalization

  * Typos ("Mounter", "pood")

  * Completely wrong paths (/inspect vs /json)

  * Missing .Method() registrations

  * Missing /libpod in some /volumes paths

  * Incorrect method declaration: /libpod/containers/.../kill
    was correct (POST) in swagger but wrong in the code itself
    (http.MethodGet). Correct the latter to MethodPost

This is two hours' work, even with a script I have that
tries to cross-check everything.

Swagger docs should not be human-maintained.

Brent Baude ddffc865f3 Rewire ListContainers for APIv2 libpod
consumers of the api remarked how they would prefer a more strongly typed data structure from list containers oon the libpod side of things.  for example, events should be consumable and consistent timestamps.  also, for the sake of compatibility, it is helpful to have the json named atttributes for Id to not be ID.

listcontainers on the libpod side no longer strongly uses the the ps cli to obtain information but we do benefit from turning on the ability to list the last X containers, something CLI does not have yet. we also flipped the bit on defaulting to truncated output in the return.

thanks to the efforts of the cockpit team to help us here.

Matthew Heon ac47e80b07 Add an API for Attach over HTTP API
The new APIv2 branch provides an HTTP-based remote API to Podman.
The requirements of this are, unfortunately, incompatible with
the existing Attach API. For non-terminal attach, we need append
a header to what was copied from the container, to multiplex
STDOUT and STDERR; to do this with the old API, we'd need to copy
into an intermediate buffer first, to handle the headers.

To avoid this, provide a new API to handle all aspects of
terminal and non-terminal attach, including closing the hijacked
HTTP connection. This might be a bit too specific, but for now,
it seems to be the simplest approach.

At the same time, add a Resize endpoint. This needs to be a
separate endpoint, so our existing channel approach does not work
here.

I wanted to rework the rest of attach at the same time (some
parts of it, particularly how we start the Attach session and how
we do resizing, are (in my opinion) handled much better here.
That may still be on the table, but I wanted to avoid breaking
existing APIs in this already massive change.
