healthcheck: stop showing wrong status when --no-healthcheck is set
Containers started with `--no-healthcheck` are configured to contain no
healthcheck and test configured as `NONE`. Podman shows wrong status as
such use cases.

Following commit fixes the faulty behavior of stauts field for
containers started with `--no-healthcheck`

podman machine: remove hostip from port
Inside the podman machine vm we always remove the hostip from the port
mapping because this should only be used on the actual host. Otherwise
you run into issues when we would bind 127.0.0.1 or try to bind a
host address that is not available in the VM.

This was already done for cni/netavark ports and slirp4netns but not for
the port bindings inside libpod which are only used as root.

[NO NEW TESTS NEEDED] We still do not have machine tests!

slirp: fix setup on ipv6 disabled systems
When enable_ipv6=true is set for slirp4netns (default since podman v4),
we will try to set the accept sysctl. This sysctl will not exist on
systems that have ipv6 disabled. In this case we should not error and
just ignore the extra ipv6 setup.

Also the current logic to wait for the slirp4 setup was kinda broken, it
did not actually wait until the sysctl was set before starting slirp.
This should now be fixed by using two `sync.WaitGroup`s.

container: workdir resolution must consider symlink if explicitly configured
While resolving `workdir` we mostly create a `workdir` when `stat`
fails with `ENOENT` or `ErrNotExist` however following cases are not
true when user explicitly specifies a `workdir` while `running` using
`--workdir` which tells `podman` to only use workdir if its exists on
the container. Following configuration is implicity set with other
`run` mechanism like `podman play kube`

Problem with explicit `--workdir` or similar implicit config in `podman play
kube` is that currently podman ignores the fact that workdir can also be
a `symlink` and actual `link` could be valid.

Hence following commit ensures that in such scenarios when a `workdir`
is not found and we cannot create a `workdir` podman must perform a
check to ensure that if `workdir` is a `symlink` and `link` is resolved
successfully and resolved link is present on the container then we
return as it is.

Docker performs a similar behviour.

Matthew Heon 4a60319ecb Remove the runtime lock
This primarily served to protect us against shutting down the
Libpod runtime while operations (like creating a container) were
happening. However, it was very inconsistently implemented (a lot
of our longer-lived functions, like pulling images, just didn't
implement it at all...) and I'm not sure how much we really care
about this very-specific error case?

Removing it also removes a lot of potential deadlocks, which is
nice.

cdoern 94df701512 Implement Podman Container Clone
podman container clone takes the id of an existing continer and creates a specgen from the given container's config
recreating all proper namespaces and overriding spec options like resource limits and the container name if given in the cli options

this command utilizes the common function DefineCreateFlags meaning that we can funnel as many create options as we want
into clone over time allowing the user to clone with as much or as little of the original config as they want.

container clone takes a second argument which is a new name and a third argument which is an image name to use instead of the original container's

the current supported flags are:

--destroy (remove the original container)
--name (new ctr name)
--cpus (sets cpu period and quota)
--cpuset-cpus
--cpu-period
--cpu-rt-period
--cpu-rt-runtime
--cpu-shares
--cpuset-mems
--memory
--run

David Gibson db4d15e852 Propagate $CONTAINERS_CONF to conmon
The CONTAINERS_CONF environment variable can be used to override the
configuration file, which is useful for testing.  However, at the moment
this variable is not propagated to conmon.  That means in particular, that
conmon can't propagate it back to podman when invoking its --exit-command.
The mismatch in configuration between the starting and cleaning up podman
instances can cause a variety of errors.

This patch also adds two related test cases.  One checks explicitly that
the correct CONTAINERS_CONF value appears in conmon's environment.  The
other checks for a possible specific impact of this bug: if we use a
nonstandard name for the runtime (even if its path is just a regular crun),
then the podman container cleanup invoked at container exit will fail.
That has the effect of meaning that a container started with -d --rm won't
be correctly removed once complete.

Matthew Heon 87cca4e5e3 Modify /etc/resolv.conf when connecting/disconnecting
The `podman network connect` and `podman network disconnect`
commands give containers access to different networks than the
ones they were created with; these networks can also have DNS
servers associated with them. Until now, however, we did not
modify resolv.conf as network membership changed.

With this PR, `podman network connect` will add any new
nameservers supported by the new network to the container's
/etc/resolv.conf, and `podman network disconnect` command will do
the opposite, removing the network's nameservers from
`/etc/resolv.conf`.

move rootless netns slirp4netns process to systemd user.slice
When running podman inside systemd user units, it is possible that
systemd kills the rootless netns slirp4netns process because it was
started in the default unit cgroup. When the unit is stopped all
processes in that cgroup are killed. Since the slirp4netns process is
run once for all containers it should not be killed. To make sure
systemd will not kill the process we move it to the user.slice.

system prune: remove all networks
podman system prune should also remove all networks. When we want to
users to migrate to the new network stack we recommend to run podman
system reset. However this did not remove networks and if there were
still networks around we would continue to use cni since this was
considered an old system.

There is one exception for the default network. It should not be removed
since this could cause other issues when it no longer exists. The
network backend detection logic ignores the default network so this is
fine.

volume: add support for non-volatile upperdir,workdir for overlay volumes
Often users want their overlayed volumes to be `non-volatile` in nature
that means that same `upper` dir can be re-used by one or more
containers but overall of nature of volumes still have to be `overlay`
so work done is still on a overlay not on the actual volume.

Following PR adds support for more advanced options i.e custom `workdir`
and `upperdir` for overlayed volumes. So that users can re-use `workdir`
and `upperdir` across new containers as well.
