Skip temp table tests for PG9.2
Added new schedule files for PG92 with skip files
Added current incorrect tests in the skipfiles
Naive Bayes: Updated tests for new MADlib commit c2cd5ca

Updated tests that correctly check the accuracy of the Naive Bayes
result. Also commented out the workaround tests since they are not the
right way to test the Naive Bayes results. We still need to add
results from external toolset to compare the absolute results from
MADlib.
Made more changes to skip_knowissues to test if kmeans tests are skipped
Generic CV: Add new test cases for cross-validation module

Added various new testcases, UDF wrapper functions, and updated the
sql.template files to reflect testing the cross-validation module
for linear and logistic regression. Cleaned the yaml files to remove
new module yaml files that were added accidentally.
Naive bayes: Commented pg test file
Changed dataset config.yaml to include data loading for all modules
PLDA init_cases updated
Test for Linear Regression w/ grouping & heteroskedasticity

Added input and output tests for Linregr with grouping and
heteroskedasticity BP test support.
Test for Linear Regression w/ grouping & hetero: Merge schedule file

Copied the case names into list_dev_regression, and then deleted the
individual schedule file for linrege w/ grouping and hetero...
Replace __cv_unique_string with __unique_string in General_CV and ridge
tests
Make ARRAY[...] expression work in MADmark

Changed MADmark source code so that kmeans accepts array[...] expression
correctly
Logistic Regression: Update resultbaseline file

Made a couple of changes in resultbaseline.sql.template to
reflect new error messages from logistic regression. Also removed
unnecessary yaml files from /schedule.
Logistic Regression: Update logregr tests to reflect new API

Logistic regression API was changed to include grouping support.
The tests have been updated to take this change into account.
Also, multiple new tests have been added to verify the results of the
module with R.
Logregr: Update test cases for grouping support in logregr

Updated all input and output tests to reflect the new API with
grouping support.
Had to change all list files for update in case names
Allow all datasets to be loaded again.
Add kmeans skipped tests to GPDB4.0, GPDB4.1,
and PG9.2 skip files
Generic CV: Add NULL grouping to CV logregr tests.
