[PATCH 2/2 v3] opensm SA DB dump/restore: added option to dump SA DB on every sweep

[Yevgeny Kliteynik <kliteyn-LDSdmyG8hGV8YrgS2mwiifqBs+8SCbDb@public.gmane.org>]

Added option 'sa_db_dump' to dump SA DB at every
sweep (both heavy and light).
The option is not exposed through OSM command line,
but only through options file.
