Tim Buckley a83e90b560 Enable CSV logging output for DStat. ...

Future work toward visualization of DevStack and devstack-gate performance
would benefit greatly from the availability of machine-parsable DStat output.
This patch outputs an additional logfile to $LOGDIR, `dstat-csv.log`, using
DStat's built-in CSV logging functionality.

An additional instance of DStat is started during start_dstat that outputs
to CSV-formatted text without `--top-cpu-adv` and `-top-io-adv` enabled, as
these plugins are currently incompatible with CSV output. To facilitate this,
a new `dstat.sh` script is added to $TOP_DIR/tools/ to act as a daemon to
manage the two processes.
