LU-18503 utils: keepalive message from ofd_access_log_reader

Checks ofd_access_log_reader for keepalive message feature
availability. Start ofd_access_log_reader with keepalive
message option if it is available.
Added tests for ofd_access_log_reader to test keepalive
message feature. Fixed a bug when trace file is opened.
Moved FATAL, ERROR, DEBUG macros to include and used FATAL
macro where possible
