This commit modifies the instruactions so that
they use the vagrant user instead of root. Also sudo is now
requierd for a significant amount of the commands.
Changed server to controlplane and node-0 to node01, and node-1 to
node02 in the documentation.
Also started reformatting to limit lines to 80 characters.
Added a section on how to enable to root account for login.
