podman exec should handle options --env foo
If the user does not specify foo=bar, then the exec code should look for the foo environment variable in its environment and pass it in. This is the way podman run works. Also added tests to make sure this all works. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com> Closes: #552 Approved by: mheon
