We have configuration information split between the README.md and
configuration documentation. A lot of it is duplicated and it shows
little organisation.
This clears the README.md of detailed configuration options and
consolidates it into the existing configuration guide. When someone
first hits the README they don't need details on changing the RPC
back-end; but more importantly this indicates clearly where we should
be adding or clarifying details.
Firstly, the detailed overview of local.conf is removed; it was
duplicated in the configuration guide. This is left as a first-level
section of that guide.
The configuration notes are divided into generic devstack things
(logging, database-backend, etc) and then the rest of the notes on
various projects' configuration options have been moved into a
dedicated sub-section "Projects".
Each project gets its own sub-sub-section. Duplicated swift guides is
consolidated into the single "Swift section". The neutron and
multi-node nodes, which were all duplicated in their more specific
dedicated guides are removed and replaced with links to those. Other
sections are moved directly.
