6f630bc09b Move OCI runtime implementation behind an interface
For future work, we need multiple implementations of the OCI
runtime, not just a Conmon-wrapped runtime matching the runc CLI.

As part of this, do some refactoring on the interface for exec
(move to a struct, not a massive list of arguments). Also, add
'all' support to Kill and Stop (supported by runc and used a bit
internally for removing containers).

5ed2de158f healthcheck: reject empty commands
An image with "HEALTHCHECK CMD ['']" is valid but as there is no command
defined the healthcheck will fail. Reject such a configuration.

Fixes #3507

dd0ea08cef healthcheck: improve command list parser
- remove duplicate check, already called in HealthCheck()
- reject zero-length command list and empty command string as errorneous

- use Docker default "/bin/sh -c" for CMD-SHELL

Fixes #3507

1be345bd9d Begin to break up pkg/inspect
Let's put inspect structs where they're actually being used. We
originally made pkg/inspect to solve circular import issues.
There are no more circular import issues.

Image structs remain for now, I'm focusing on container inspect.

bb69004b8c podman health check phase3
podman will not start a transient service and timer for healthchecks.
this handles the tracking of the timing for health checks.

added the 'started' status which represents the time that a container is
in its start-period.

the systemd timing can be disabled with an env variable of
DISABLE_HC_SYSTEMD="true".

added filter for ps where --filter health=[starting, healthy, unhealthy]
can now be used.

03716cf7f3 healtcheck phase 2
integration of healthcheck into create and run as well as inspect.
healthcheck enhancements are as follows:

* add the following options to create|run so that non-docker images can
define healthchecks at the container level.
  * --healthcheck-command
  * --healthcheck-retries
  * --healthcheck-interval
  * --healthcheck-start-period

* podman create|run --healthcheck-command=none disables healthcheck as
described by an image.
* the healthcheck itself and the healthcheck "history" can now be
observed in podman inspect
* added the wiring for healthcheck history which logs the health history
of the container, the current failed streak attempts, and log entries
for the last five attempts which themselves have start and stop times,
result, and a 500 character truncated (if needed) log of stderr/stdout.

The timings themselves are not implemented in this PR but will be in
future enablement (i.e. next).

598bde52d0 podman healthcheck run (phase 1)
Add the ability to manually run a container's healthcheck command.
This is only the first phase of implementing the healthcheck.
Subsequent pull requests will deal with the exposing the results and
history of healthchecks as well as the scheduling.
