Subject: make NIS Plugin and Schema Compatibility Plugin betxn aware

When NIS Plugin and Schema Compatibility Plugin config entries include
  nsslapd-pluginbetxn: on
  (the value could be yes, true or 1, too),
the plugins' update callbacks (add, delete, modify, and modrdn) are
called at the betxn pre/postop timing. By default, the value of
nsslapd-pluginbetxn is off.
