Add a new service reaper package. Podman currently does not reap all
child processes. The slirp4netns and rootlesskit processes are not
reaped. The is not a problem for local podman since the podman process
dies before the other processes and then init will reap them for us.
However with podman system service it is possible that the podman
process is still alive after slirp died. In this case podman has to reap
it or the slirp process will be a zombie until the service is stopped.
The service reaper will listen in an extra goroutine on SIGCHLD. Once it
receives this signal it will try to reap all pids that were added with
`AddPID()`. While I would like to just reap all children this is not
possible because many parts of the code use `os/exec` with `cmd.Wait()`.
If we reap before `cmd.Wait()` things can break, so reaping everything
is not an option.

if LISTEN_FDS is specified by systemd, we need to use the first fd
after the std files (so fd=3) to read from the activation socket
instead of manually opening the UNIX socket.

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

Currently the service is attempting to prompt on shortname expansion if you run
with a terminal. This change will cause the service to default to no terminal
and not prompt.

this enables the ability to connect and disconnect a container from a
given network. it is only for the compatibility layer. some code had to
be refactored to avoid circular imports.
additionally, tests are being deferred temporarily due to some
incompatibility/bug in either docker-py or our stack.

Stop over wrapping API Calls
The API calls will return an appropriate error, and this wrapping
just makes the error message look like it is stuttering and a
big mess.

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].

We need to default to building podman. If you specify no build
tags you will not build podman, not podman-remote.
Just using remote flag to indicate podman-remote and !remote for
podman.

While this commit was initially meant to fix#5847, it has turned into a
bigger refactoring which I did not manage to break into smaller pieces:
* Fix#5847 by refactoring the image-removal logic.
* Make the api handler for image-removal use the ABI code. This way,
both (i.e., ABI and Tunnel) end up using the same code. Achieving
this code share required to move some code around to prevent circular
dependencies.
* Everything in pkg/api (excluding pkg/api/types) must now only be
accessed from code using `ABISupport`.
* Avoid imports from entities on handlers to prevent circular
dependencies.
* Move `podman system service` logic into `cmd` to prevent circular
dependencies - it depends on pkg/api.
* Also remove the build header from infra/abi files. It will otherwise
confuse swagger and other tools; errors we cannot fix as go doesn't
expose a build-tag env variable.
