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. Update of params.pp is managed in openstack-puppet-ci.git
