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

Deprecate SCREEN_LOGDIR in favor of LOGDIR

This is the first step in the log file cleanup.  If SCREEN_LOGDIR
is still set, symlinks will be created in the old screen log directory
so things like the devstack-gate log collector continues to work.

Install prettytable>=0.7 to satisfy pip 6/PEP 440

other things can't write to as the stack user later.
