this pr has the basic plumbing that allows the e2e machine tests to run
with the hyperv provider.
it requires a special fcos image right now because gvforwarder was not
in the upstream fcos images for hyperv.
changed the way "provider" is set; moved GetProvider functions to
pkg/machine/provider. provider is now set at the machine level.

Therefore, an additional nil check for before the loop is unnecessary.

Add new --farm flag to podman system connection add so that
a user can add a new connection to a farm immediately.
Update system connection remove such that when a connection is
removed, the connection is also removed from any farms that have it.
Add docs and tests for these changes.

`podman system service` + TCP is not a configuration we should be
recommending. There was already language about this in the
manpages, but it was not sufficient in explaining how bad of an
idea this is. Expand the manpage warnings, add a dedicated
heading so people notice, and add a warning every time the
service starts with a TCP URL that directs people to the manpage
to see that explanation.

This adds the 'system service' command to the build on FreeBSD and
suppresses the call to servicereaper.Start which is only needed to
support slirp4netns on Linux. A stub for compat.StatsContainer is also
added - stats are still supported via the libpod.StatsContainer API
call.

To debug a deadlock, we really want to know what lock is actually
locked, so we can figure out what is using that lock. This PR
adds support for this, using trylock to check if every lock on
the system is free or in use. Will really need to be run a few
times in quick succession to verify that it's not a transient
lock and it's actually stuck, but that's not really a big deal.

This is a general debug command that identifies any lock
conflicts that could lead to a deadlock. It's only intended for
Libpod developers (while it does tell you if you need to run
`podman system renumber`, you should never have to do that
anyways, and the next commit will include a lot more technical
info in the output that no one except a Libpod dev will want).
Hence, hidden command, and only implemented for the local driver
(recommend just running it by SSHing into a `podman machine` VM
in the unlikely case it's needed by remote Podman).
These conflicts should normally never happen, but having a
command like this is useful for debugging deadlock conditions
when they do occur.

system reset it says it will delete containers, images, networks, etc...
However it will also delete the graphRoot and runRoot directories.
Normally this is not an issue, however in same cases these directories
were set to the users home directory or some other important system
directory.
As first step simply show the directories that are configured and thus
will be deleted by reset. As future step we could implement some
safeguard will will not delete some known important directories however
I tried to keep it simple for now.

when running rootless on cgroupv1, Podman+OCI runtime do not setup a
separate cgroup for the container. Spawned containers will run in the
same cgroup as the podman system service process, thus will be killed
when the cgroup is destroyed, as it is the case when running as a

The current code modifies a global variable which works but is bad
design since it could be uses elsewhere. Since we just exit after the df
command this is not an issue right now but it could become one in the
future.
A better fix is to implement a custom `MarshalJSON()` method on the
struct which will be called if this struct will be marshaled.

Since we open /dev/null to set it as STDIN we can close it after the
dup2() call. Using defer is not good enough since this function will
never exit since the http server will block. This is not a problem but
it reduces the open fds from the service by one.

This just calls GC on the local storage, which will remove any leftover
directories from previous containers that are not in the podman db anymore.
This is useful primarily for transient store mode, but can also help in
the case of an unclean shutdown.
Also adds some e2e test to ensure prune --external works.

Use `Default()` instead of re-loading containers.conf.
Also rework how the containers.conf objects are handled for parsing the
CLI. Previously, we were conflating "loading the defaults" with
"storing values from the CLI" with "libpod may further change fields"
which ultimately led to various bugs and test failues.
To address the issue, separate the defaults from the values from the CLI
and properly name the fields to make the semantics less ambiguous.
[NO NEW TESTS NEEDED] as it's not a functional change.

Fix two bugs in `system df`:
1. The total size was calculated incorrectly as it was creating the sum
of all image sizes but did not consider that a) the same image may
be listed more than once (i.e., for each repo-tag pair), and that
b) images share layers.
The total size is now calculated directly in `libimage` by taking
multi-layer use into account.
2. The reclaimable size was calculated incorrectly. This number
indicates which data we can actually remove which means the total
size minus what containers use (i.e., the "unique" size of the image
in use by containers).
NOTE: The c/storage version is pinned back to the previous commit as it
is buggy. c/common already requires the buggy version, so use a
`replace` to force/pin.

I patched report.Formatter to correctly handle newlines[1]. Since we
cannot fix this with report.Template we have to migrate all users to
report.Formatter. This ensures consistent behavior for all commands.
This change does not change the output.
