apache docs should be proxy only

[clayg]

The Apache Deployment Guide docs [1] - need to be updated after we started using 100-continue headers in the storage servers [2]. Since the 100-continue headers are eventlet.wsgi only - the object-server nodes (EC and Replicated) must run under eventlet.wsgi.

N.B. Everyone assumes devstack's Apache support for Swift is broken [3] - and fixing devstack might be the quickest way to get Swift+Apache up and going
