Dean Troyer ad5cc986d8 Rename screen logfiles
This renames the log files in logs/screen that contain timestamps to put
the timestamp after '.log' and '.log.summary' in the names.  This will
simplify devstack-gate's search for log files to copy to '*.log'.

dstat.txt is also renamed to dstat.log

Make LOGDIR and LOGFILE local
