XXX rapid-cdn: Clean up instance-master.cfg.in

Cleanups:

 * dropped needless definition of aibcc_enabled
 * renamed master_partition_monitor_monitor_httpd_port to
   MASTER_PARTITION_MONITOR_HTTPD_PORT
 * convert buildout comments to Jinja2 comments
 * strip whitespaces, so that generated file is readable
 * correctly indent on Jinja2 not on buildout
 * drop obvious comments
 * minimize amount of variables, by dropping used only once
 * pass all modules with _module suffix
 * avoid passing needless software_type
 * group definition of all globals into one place
 * name all globals with UPPERCASE

XXX: Clean up until it will be possible to modify it a lot
