Title: Feature: rt support in sysguard module

Two new directives are introduced:
*) sysguard_mode and/or
*) sysguard_rt rt=time period=time action=some_location

This feature introduces the ability to limit requests based on "rt".
Also, all the measurements can be considered in an "and" or "or"
relationship due to the new "sysguard_mode" directive.

Test cases are included.
