Optimize perm_begin and perm_end

Optimize perm_begin and perm_end

[Issue#]        SSDWSSP-596
[Bug/Feature]   Database operations executed in perm_begin and perm_end
                are very slow.
[Cause]         All the rules were calculated every perm_end.
[Solution]      Calculate only modified rules.
[Verification]  Build, install, run tests - to check correctness.
                Compare speed of application installation and
                deinstallation before and after library update.
                Make sure a database is exactly the same as in new
                image (running our tests adds a lot of new rules).
                I've notices 2x - 7x speedup (depending on the number of
                modified rules).
