When making containers, we want to lock all named volumes we are
adding the container to, to ensure they aren't removed from under
us while we are working. Unfortunately, this code did not account
for a container having the same volume mounted in multiple places
so it could deadlock. Add a map to ensure that we don't lock the
same name more than once to resolve this.

we need to migrate play kube away from using the old container creation
method. the new approach is specgen and this aligns play kube with
container creation in the rest of podman.

As of this commit, in Fedora 33, without without `CAP_NET_ADMIN` and
`CAP_NET_RAW`, require setting `net.ipv3.ping_group_range` in order for
the `ping` command to work inside a container. However, not all images
`ping` are created equal. For whatever reason, the busybox version in
the busybox container image, does not function. Switch to the Alpine
image's busybox ping, which seems to work fine.

Using a function like ContainSubstring or Equal is better because if
the test fails it will log a descriptive error that includes the
actual string generated during the test. This is more helpful than a
function like BeTrue that will only indicate that an assertion failed
without giving further details of the failure.

When --userns=keep-id is used, Podman is supposed to set up the home
directory of the user inside the container to match that on the host
as long as the home directory or any of its parents are marked as
volumes to be bind mounted into the container.
Currently, the test only considers the case where the home directory
itself is bind mounted into the container. It doesn't cover the Podman
code that walks through all the bind mounts looking for ancestors in
case the home directory itself wasn't specified as a bind mount.
Therefore, this improves the existing test added in commit
6ca8067956 ("Setup HOME environment when using --userns=keep-id")
Note that this test can't be run as root. The home directory of the
root user is /root, and it's parent is /. Bind mounting the entire /
from the host into the container prevents it from starting:

When creating a container in a pod the podname was always set as

Followon to #7965 (mirror registry). mirror.gcr.io doesn't
cache all the images we need, and I can't find a way to
add to its cache, so let's just use quay.io for those
images that it can't serve.
Tools used:
skopeo copy --all docker://docker.io/library/alpine:3.10.2 \
docker://quay.io/libpod/alpine:3.10.2
...and also:
docker.io/library/alpine:3.2
docker.io/library/busybox:latest
docker.io/library/busybox:glibc
docker.io/library/busybox:1.30.1
docker.io/library/redis:alpine
docker.io/libpod/alpine-with-bogus-seccomp:label
docker.io/libpod/alpine-with-seccomp:label
docker.io/libpod/alpine_healthcheck:latest
docker.io/libpod/badhealthcheck:latest
Since most of those were new quay.io/libpod images, they required
going in through the quay.io GUI, image, settings, Make Public.

podman inspect only had the capabilities to inspect containers and images. if a user wanted to inspect a pod, volume, or network, they would have to use `podman network inspect`, `podman pod inspect` etc. Docker's cli allowed users to inspect both volumes and networks using regular inspect, so this commit gives the user the functionality
If the inspect type is not specified using --type, the order of inspection is:
containers
images
volumes
networks
pods
meaning if container that has the same name as an image, podman inspect would return the container inspect.
To avoid duplicate code, podman network inspect and podman volume inspect now use the inspect package as well. Podman pod inspect does not because podman pod inspect returns a single json object while podman inspect can return multiple)

Detached containers and detach keys are only created with the podman run, i
exec, and start commands. We do not store the detach key sequence or the
detach flags in the database, nor does Docker. The current code was ignoreing
these fields but documenting that they can be used.
Fix podman create man page and --help output to no longer indicate that
--detach and --detach-keys works.
