[ros_bridge][QNX log fetch] Add archive feature to save disk space.

[ros_bridge][QNX log fetch] With 'archive' option, remove *.log files to save disk space.

[ros_bridge][QNX log fetch] Save the archived logs file to the same dir where raw log files are (/opt/jsk/var/log).
This way it'll be easier in the future to look for the older log file archives once their raw log files are removed.

[ros_bridge][QNX log fetch] Archive feature now can specify the period, instead of text matching.
