Fix SUSE Install Guide: Placement port
Fix SUSE Install Guide: Placement port

The bug report says all:
"There is a mismatch configuration for placement.
 In the controller configuration, the guide suggests endpoints creation
 pointing to port 8778, however in the default file provided in SLES 12
 SP3, the port used is 8780."

Fix documentation to match sample file.
