Neutron API Section Added

Change-Id: I53d05ef30665f26226054baf2f7e71ef824ad943
Corrected 'rpc_backend' in Glance installation section

I corrected the 'rpc_backend' configuration key in
/etc/glance-api.conf to use 'rabbit' and 'qpid' values from Oslo.
I also removed extraneous AMQP configuration from
/etc/glance-registry.conf.
