Podman build does not respect log-level flag

[mheon]

Podman build does not pass the --log-level global flag into Buildah, so debugging output will only occur for Podman itself.

I haven't checked, but I suspect other global flags are also not respected

Most if not all the global flags are indeed not respected. I'll work on that, nice catch @mheon.

@mheon --log-level=debug should work now in podman. However that's the only error level logging that Buildah does atm, so anything else passed in is a no-op. I also turned on the flags that are common between both. That was in #312. More to be added.

@TomSweeneyRedHat I think we can say #312 fixed this issue. Closing.
