Fixes a number of technical issues with the api-ref section
including:
- Added missing headers
- The header descriptions were made specific to whether they
are used in requests or responses and the verb in question
(example: Content-Length in object HEAD is the object size,
not the response body length).
- Added references to API features such as bulk delete.
- Many typographical fixes (e.g., spaces in the middle
of header names)
- Restored xml and json account/container listing
examples.
The following areas were not updated and it is proposed
to defer them to a subsequent update. This is because
I don't have time or their merit is debatable:
- ACLs (as used in a Keystone context) are not
described.
- Account create/delete is not described.
- I left List Endpoints as-is.
