podman: split env variables in env and overrides
There are three different priorities for applying env variables:

1) environment/config file environment variables
2) image's config
3) user overrides (--env)

The third kind are known to the client, while the default config and image's
config is handled by the backend.

Ed Santiago 3d1bff6db9 man page cross-reference fixes: part 2
The other direction: fix or clean up elements documented in
man pages but which did/do not exist in actual podman:

  * runlabel: add missing "-n" alias for --name

And, remove man page entries for nonexistent options:

  * podman commit: --iidfile
  * podman container runlabel: --rootfs, --storage
  * podman create: --cpu-count

There are two problems I don't know how to deal with. Both
are related to main_local.go:rootCmd.PersistentFlags() :

  1) podman-build.1.md documents --cni-config-dir and
     --runtime options, but these are not actually options
     under podman build; they are global options. The
     documentation in this man page differs from that
     under podman-build.

  2) podman ps implements a binary --namespace option,
     but this option does not (cannot?) appear in --help
     because there's a global --namespace string option
     and Cobra somehow gets confused about this.

Do we really intend for global options to be parsed on
the right-hand side of subcommands? This strikes me as
unintuitive and potentially confusing, although the
fact that it has taken me this long to discover it
suggests that it's not _that_ confusing.

Suggestions welcome. I can file issues for 1/2 above,
or simply teach my script to special-case ignore them.

Ed Santiago 281def2647 man pages: fix inconsistencies
I wrote a script to cross-reference podman --help against
man pages. It found a bunch of inconsistencies fix them:

 * options missing from man pages
 * options misspelled or misformatted in man pages (usually
   misplaced asterisks or missing dashes, but see --dns-opt)
 * one spurious comma in the actual source file --help

This is a fix in which I iterate over 'podman CMD --help'
and check for presence in man pages. The other way around
(look for flags in man pages, check podman CMD --help)
is probably impossible: there are too many special cases

Valentin Rothberg f3f4c54f2a policy for seccomp-profile selection
Implement a policy for selecting a seccomp profile.  In addition to the
default behaviour (default profile unless --security-opt seccomp is set)
add a second policy doing a lookup in the image annotation.

If the image has the "io.containers.seccomp.profile" set its value will be
interpreted as a seccomp profile.  The policy can be selected via the
new --seccomp-policy CLI flag.

Once the containers.conf support is merged into libpod, we can add an
option there as well.

Note that this feature is marked as experimental and may change in the
future.

namespaces: by default create cgroupns on cgroups v2
change the default on cgroups v2 and create a new cgroup namespace.

When a cgroup namespace is used, processes inside the namespace are
only able to see cgroup paths relative to the cgroup namespace root
and not have full visibility on all the cgroups present on the
system.

The previous behaviour is maintained on a cgroups v1 host, where a
cgroup namespace is not created by default.
