If a javascript job produces web content that should be deployed (such
as zuul-web or storyboard-webclient) we should collect that in the post
step of the job and put it into the html/ directory.
While in there, add a bunch of get_*: false entries for the stat calls.
Calculating the md5 and whatnot is expensive, and we should really
always set them to false unless we're *using* the hash values.
