This reverts commit 30f3760e.

+ fixed algorithm recalculating szbase paths from patches in ss client: curr_path = patch(prev_path)
+ bug affected szbase paths longer than 126. Now the algorithm should support properly paths of length up to 126*126

displaying non fixed data

yet another timer that allows us to specify that we want to add delay
in-between queries to the consecutive units on the same connection

- iks server can now configure sz4 engine to use live cache
- fix for a bug in an iks-server where asynchronous erase_cmd operation
  could be performed on a disconnected (and thus deleted) ProtocolLocation
  object
- fix some live cache corner cases handling

over/underflow value logging

some simplification of templating in sz4 code

* rsyslog is not required by SZARP, so szarp-base package should be able
  to successfully finish 'configure' step without rsyslogd.

+ no logs (and no meil) if no packages are to be installed
+ full logs if any package is installed
+ made using simulated install
