0.4.1

More fixes and features in the August release...thank you for all of the contributions!

The most notable feature in this release are named volumes (`container volume create`). One difference between named volumes in `container` and in other systems is that you can't read-write a named volume across multiple running containers (VMs).

Why no 0.4.0? We had to discard that tag due to a couple test regressions.

## Highlights

* Core
  * [`systemd` can run in containers](https://github.com/apple/container/issues/92)
