This is now implemented.

A primitive version of this is also implemented now.  Every generated
script supports containerization when GWL_CONTAINERIZE is set.  (I don’t
expect users to set this manually, but to have a “driver” script that
sets it according to user configurations.)

This is one of the use cases that needs to be understood better.  I
would like different execution backends to be available in the generated
job scripts without having to make this decision at preparation time.  I
want developers to be able to distribute workflow artifacts that are
flexible enough to execute the workflow in different ways, so I think
container support must be switchable at runtime.
