podmanV2: implement logs

Implement the `podman {container} logs` for the v2 client. The remote
client does not yet support it.  There's some more work needed for the
rest api; some options are missing (e.g., printing names) while others
are broken (e.g., the until http parameter).

The remote parts will be tackled in a future change.
