Description of problem:
------------------------

Scaling section( "3.8 scaling" )  in the deployment guide needs improvement

This section mentions initial deployment starts with 1 or 3 node, but using ‘Automating RHHI deployment’ using ansible playbooks, it’s possible to deploy 3, 6, 9, 12 nodes in one shot

Actual content
--------------
"You cannot create a volume that spans more than 3 nodes at creation time; you must create a 3-node volume first and then expand it across more nodes as necessary."
     
Expected content:
--------------------
Above statement in this section is true only when the deployment is initiated using web console
