* Make legacy docs asciidoctor compatible
This modifies the legacy client documentation so that it is is
compatible with Asciidoctor. With these changes asciidoctor renders the
same way as asciidoc, module spacing and a couple of auto-generated ids.
I'm willing to ignore the auto-generated anchors because these are
legacy docs.
* Updated configuration template
