Matthew Heon 5ed23327a9 Rename libpod.Config back to ContainerConfig
During an earlier bugfix, we swapped all instances of
ContainerConfig to Config, which was meant to fix some data we
were returning from Inspect. This unfortunately also renamed a
libpod internal struct for container configs. Undo the rename
here.

Matthew Heon 97681a5f2b Move lock init after tmp dir is populated properly
Don't initialize the lock manager until almost the end of libpod
init, so we can guarantee our tmp dir is properly set up and
exists. This wasn't an issue on systems that had previously run
Podman, but CI caught it.

Fixes to handle /dev/shm correctly.
We had two problems with /dev/shm, first, you mount the
container read/only then /dev/shm was mounted read/only.
This is a bug a tmpfs directory should be read/write within
a read-only container.

The second problem is we were ignoring users mounted /dev/shm
from the host.

If user specified

podman run -d -v /dev/shm:/dev/shm ...

We were dropping this mount and still using the internal mount.

umohnani8 4c70b8a94b Add "podman volume" command
Add support for podman volume and its subcommands.
The commands supported are:
	podman volume create
	podman volume inspect
	podman volume ls
	podman volume rm
	podman volume prune

This is a tool to manage volumes used by podman. For now it only handle
named volumes, but eventually it will handle all volumes used by podman.

baude 2dd9cae37c rm -f now removes a paused container
We now can remove a paused container by sending it a kill signal while it
is paused.  We then unpause the container and it is immediately killed.

Also, reworked how the parallelWorker results are handled to provide a
more consistent approach to how each subcommand implements it. It also
fixes a bug where if one container errors, the error message is duplicated
when printed out.

Matthew Heon 140f87c474 EXPERIMENTAL: Do not call out to runc for sync
When syncing container state, we normally call out to runc to see
the container's status. This does have significant performance
implications, though, and we've seen issues with large amounts of
runc processes being spawned.

This patch attempts to use stat calls on the container exit file
created by Conmon instead to sync state. This massively decreases
the cost of calling updateContainer (it has gone from an
almost-unconditional fork/exec of runc to a single stat call that
can be avoided in most states).

Matthew Heon 2c7f97d5a7 Add ContainerStateExited and OCI delete() in cleanup()
To work better with Kata containers, we need to delete() from the
OCI runtime as a part of cleanup, to ensure resources aren't
retained longer than they need to be.

To enable this, we need to add a new state to containers,
ContainerStateExited. Containers transition from
ContainerStateStopped to ContainerStateExited via cleanupRuntime
which is invoked as part of cleanup(). A container in the Exited
state is identical to Stopped, except it has been removed from
the OCI runtime and thus will be handled differently when
initializing the container.

Daniel J Walsh 3a90b5224d Returning joining namespace error should not be fatal
I got my database state in a bad way by killing a hanging container.

It did not setup the network namespace correctly

listing/remove bad containers becomes impossible.

podman run alpine/nginx
^c
got me in this state.

I got into a state in the database where
podman ps -a
was returning errors and I could not get out of it,  Makeing joining the network
namespace a non fatal error fixes the issue.
