Add support for measuring storage performance use fio

A simple test case is added that will test writes to ephemeral storage.
See samples/fio.yaml

The Fio test type can also be used to test block storage, just modify
the "filename" argument.

+# Sample benchmark task config file
+# measure storage performance using fio
+#
+# For this sample just like running the command below on the test vm and 
+# getting benchmark info back to the yardstick.
+#
+# sudo fio -filename=/home/ec2-user/data.raw -bs=4k -rw=write -ramp_time=10 \
+#          -runtime=60 -name=yardstick-fio -ioengine=libaio -direct=1 \
+#          -group_reporting -numjobs=1 -time_based --output=yardstick-fio.log
+#
+# When the above fio command done, the yardstick-fio.log file will contain 
+# information like below and the benchmark script will take iops, throughput 
+# and latency info marked with "" to create json style output.
