Add a hidden flag to set the database backend and plumb it into
podman-info. Further add a system test to make sure the flag and the
info output are working properly.
Note that the test may need to be changed once we settled on how
to test the sqlite backend in CI.

If the run errors, cobra does not execute post runs. It is a somehow
known issue (https://github.com/spf13/cobra/issues/914) but problematic
for Podmand as the runtime is shutdown during post run.
Since some commands overwrite the post run and a general lack in cobra
of post runs on errors, move the shutting down the engines directly into
Execute. Fixing the issue may fix a number of flakes.
Note that the shutdowns are NOPs for the remote client.

This handles the transient store options from the container/storage
configuration in the runtime/engine.
Changes are:
* Print transient store status in `podman info`
* Print transient store status in runtime debug output
* Add --transient-store argument to override config option
* Propagate config state to conmon cleanup args so the callback podman
gets the same config.
Note: This doesn't really change any behaviour yet (other than the changes
in containers/storage).

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.

--debug should not be a global flag, you can only use this as podman
--debug never podman ps --debug. This matches docker and allows us to

implement new ssh interface into podman
this completely redesigns the entire functionality of podman image scp,
podman system connection add, and podman --remote. All references to golang.org/x/crypto/ssh
have been moved to common as have native ssh/scp execs and the new usage of the sftp package.
this PR adds a global flag, --ssh to podman which has two valid inputs `golang` and `native` where golang is the default.
Users should not notice any difference in their everyday workflows if they continue using the golang option. UNLESS they have been using an improperly verified ssh key, this will now fail. This is because podman was incorrectly using the
ssh callback method to IGNORE the ssh known hosts file which is very insecure and golang tells you not yo use this in production.
The native paths allows for immense flexibility, with a new containers.conf field `SSH_CONFIG` that specifies a specific ssh config file to be used in all operations. Else the users ~/.ssh/config file will be used.
podman --remote currently only uses the golang path, given its deep interconnection with dialing multiple clients and urls.
My goal after this PR is to go back and abstract the idea of podman --remote from golang's dialed clients, as it should not be so intrinsically connected. Overall, this is a v1 of a long process of offering native ssh, and one that covers some good ground with podman system connection add and podman image scp.

There are at least two runtimes that support checkpoint and restore:
runc and crun. Although the checkpoints created by these are almost
compatible, it is not (yet) possible to restore a checkpoint created
with one runtime with the other runtime. To make checkpoint/restore
usage more comfortable this adds code to look into the checkpoint
archive during restore and to set the runtime to the one used during
checkpointing.
This also adds a check, if the user explicitly sets a runtime during
restore, that the runtime is also the same as used during checkpointing.
If a different runtime is selected than the one used during
checkpointing the restore will fail early.
If runc and crun will create compatible checkpoints in the future the
check can be changed to treat crun and runc as compatible
checkpoint/restore runtimes.
