make image and container option builder interfaces consistent (#211)

`ContainerListOptionsBuilder::all()` took no arguments, assuming a true
value. However, `ImageListOptionsBuilder::all()` accepts a boolean.

To make these consistent, the latter no longer accepts a boolean and,
like the former, assumes true.
