RTD does not support installing system packages, the only ways to install
dependencies are setuptools and pip. while ditaa is a tool written in
Java. so we need to find a native python tool allowing us to render ditaa
images. plantweb is able to the web service for rendering the ditaa
diagram. so let's use it as a fallback if "ditaa" is not around.
also start a new line after the directive, otherwise planweb server will
return 500 at seeing the diagram.

cross-reference the documentatation on OpenStack, and on CephX.

The ceph-ansible ceph-iscsi support does not allow setting up iscsi
objects. It must be done through gwcli like is done in the container
case. This drops the iscsi object related settings and admin info for
it.

The old note made it sound like we weren't crash-consistent, and had a
confusing section about needing to clone before mounting.
You *do* need to clone the snapshot before mounting it, but that has
nothing to do fs freezing or consistency.
