This commit remove duplicate mysql_password param. And standardize
mysql_password (renamed to mysql_root_password), and clarify
mysql_sys_maint param (renamed to mysql_sys_maint_password), a new
param is now added (mysql_sys_maint_user).
This commit also add a bind option to xinetd configuration file. (The
default value is setup to ::ipaddress). And cleanup cluster configs to
avoid namespaces collisions with corosync cluster.
