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.
