Title: CLIMATE-483 - Add basic PatternCorrelation metric

- Rename old PatternCorrelation metric to TemporalPatternCorrelation
since it does an annual reshaping of the datasets before doing a
comparison and that isn't adequately reflected in the metric's name.
The new name also falls in line with the functionality of the
TemporalStdDevRatio metric which also does such a rebin.
- Add basic PatternCorrelation metric that uses
scipy.stats.mstats.linregress to return the r_value for the reference
and target datasets. Note, the metric no longer returns a tuple of
values. It now only returns the r_value. This falls much more in line
with the metrics name in my opinion.
