This PR makes the "Ceph OSDs" and "MDSs" bullet points
parallel by naming "object storage daemon" before referring
to the (admittedly more common and colloquial, but surely

I'm changing "3" to "three" for two reasons:
1. It's correct.
2. This allows me to test backports into Octopus, Pacific, and Quincy.
I am particularly interested to see what happens when I attempt
the backport into Octopus, because backports into Octopus have
failed. This will provide me with another unit of data.

RTD does not support installing system packages, the only ways to install
dependencies are setuptools and pip. while ditaa is a tool written in

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.

The documentation currently refers to Ceph Manager Modules as
"plugins" in many places, while the command line interface uses
"module" to enable/disable modules. Replaced all occurences
of "plugin" with "module" in the docs, to avoid confusion and to
be in alignment with the CLI. Also fixed the capitalizations of some
module chapters.

This is a method of standardizing the usage of OSD so that "Ceph OSD"
is the daemon, and OSD maintains its industry standard usage of Object
Storage Device.
