A CNI container image is required for rootless networking
in V2.2.1 (RHEL 8.3.1) and through v3.0.1. Add a note in the
troubleshooting guide with a pointer to the documenation
for that.

Users coming e.g. from Docker do not always read the manual and
expect podman to not require sudo or uidmap, for them the default
message is not very helpful:
Error: Cannot connect to the Podman socket, make sure there is a Podman REST API service running.:
cannot find newuidmap: exec: "newuidmap": executable file not found in $PATH
Adding a bit more context to this would help to nudge them into the
right direction and tell them what to look for in the documentation:
command required for rootless mode with multiple IDs: exec: "newuidmap": executable file not found in $PATH

[NO TESTS NEEDED]
Systemd is now complaining or mentioning /var/run as a legacy directory.
It has been many years where /var/run is a symlink to /run on all
most distributions, make the change to the default.

We've recently had a number of issues reported against our
pre-fabricated images on quay.io and a couple of rhel repositories
throwing a fuse error when run:
```
fuse: device not found, try 'modprobe fuse' first
```
The tip on modprobe fuse is not always seen by or displayed to
the end user. Adding a couple of doc pointers to hopefully help.
Arises from this BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1867892
and several others.

Add notes to the podman-create and podman-run man pages
to note that ports do not need to be published and should not
be, for containers that will be part of a pod.

Add an additional troubleshooting item to warn users that Secure Boot
can prevent Podman from running containers. The error messages and
initial debugging steps don't make it clear that this all stems from a
BIOS setting. Hopefully adding this item to the troubleshooting doc
will avoid future headaches.

Replaces 'skopeo-containers' with 'containers-common' in the files that
I feel comfortable changing it in. There are a number of rpm building
related files that still have it, but I was hesitant to do so.

Lots of users are attempting to run systemd within a container. They are
being blocked from running SELinux systems since they need the
container_manage_cgroup which is not enabled by default.

A common failure with people building container images is the
creation of large sparse files, particularly useradd creating
the lastlog file.
This PR Documents the failures.
