We cannot use the RunDir for writing the conmon.pid file as we might
not be able to read it before we join a namespace, since it is owned
by the root in the container which can be a different uid when using
uidmap. To avoid completely the issue, we will just write it to the
static dir which is always readable by the unprivileged user.

add the ability for users to specify more than one container at a time
while using podman logs. If more than one container is being displayed,
podman will also prepend a shortened container id of the container on
the log line.
also, enabled the podman-remote logs command during the refactoring of
the above ability.

SCTP is already present and enabled in the CNI plugins, so all we
need to do to add support is not error on attempting to bind
ports to reserve them.
I investigated adding this binding for SCTP, but support for SCTP
in Go is honestly a mess - there's no widely-supported library
for doing it that will do what we need.
For now, warn that port reservation for SCTP is not supported and
forward the ports.

When creating a new image volume to be mounted into a container, we need to
make sure the new volume matches the Ownership and permissions of the path
that it will be mounted on.
For example if a volume inside of a containre image is owned by the database
UID, we want the volume to be mounted onto the image to be owned by the
database UID.

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).

In lipod, we now log major events that occurr. These events
can be displayed using the `podman events` command. Each
event contains:
* Type (container, image, volume, pod...)
* Status (create, rm, stop, kill, ....)
* Timestamp in RFC3339Nano format
* Name (if applicable)
* Image (if applicable)
The format of the event and the varlink endpoint are to not
be considered stable until cockpit has done its enablement.

When mounting a tmpfs, runc attempts to make the directory it
will be mounted at. Unfortunately, Golang's os.MkdirAll deals
very poorly with symlinks being part of the path. I looked into
fixing this in runc, but it's honestly much easier to just ensure
we don't trigger the issue on our end.

When sourcing from an image, we need to grab its entrypoint first
and then add command on to mimic the behavior of Docker.
The default Kube pause image just sets ENTRYPOINT, and not CMD,
so nothing changes there, but this ought to fix other images
(for example, nginx would try to run the pause command instead of
an nginx process without this patch)

The logic of deleting and recreating /etc/hosts and

the files - when we don't, it just removes them, and there's

When looking up a container or pod by from user input, we handle
collisions between names and IDs differently than Docker at
present.
In Docker, when there is a container with an ID starting with
"c1" and a container named "c1", commands on "c1" will always act
on the container named "c1". For the same scenario in podman, we
throw an error about name collision.
Change Podman to follow Docker, by returning the named container
or pod instead of erroring.
This should also have a positive effect on performance in the
lookup-by-full-name case, which no longer needs to fully traverse
the list of all pods or containers.
