> Right now the timestamp is always latest. With this patch, users can select timestamps
they want.
> In this patch, 4 parameters, "timestamp", "minTimestamp", "maxiTimestamp" and "maxVersions"
are added to HBaseSparkConf. Users can select a timestamp, they can also select a time range
with minimum timestamp and maximum timestamp. A new test for selecting records with different
timestamps is added.
