nscd.conf.5: Add max-db-size and auto-propagate descriptions, default values, + misc
* added missing valid services (services and netgroup) * added many default values for options * reordered options according to the nscd.conf file (logical order) * added 2 missing options: max-db-size and auto-propagate All changes are based on nscd.conf file [1] and source code for nscd [2] (e.g. nscd.h for default values, etc.) Original email for this update can be found here [3], however patch attached to this bugzilla is newer.
