I'm a bit weary about this series. In the past we had cases where
people will set the variable to empty string and/or 0 and expect
things to work.

IIRC the older Intel QA team was using it, not sure about now. Either
way it's great to confirm with a few people before pushing this.

That aside, env_var_as_boolean() treats 'yes', '1' and 'true' in
identical manner. Perhaps we can state what a "boolean variable" is
and use that reference through the documentation?
