Patch Release for Feature Sture

This is a patch release for 2.4.0-k8

The following features were added:

• Drift detection (@sergioferragut )
• Organized utilities modules for helpful functions of drift detection and training view SQL creation (@Ben-Epstein , @sergioferragut )

The following was fixed

• Case sensitivity: The database's case sensitive column and table names were causing searchability issues. To remedy this, all column names, schema names, and table names are stored as UPPERCASE in the metadata, to match the default state of the database storage. (@sergioferragut )
• datetime.min (0001-01-01 00:00:00) was causing problems when Spark tried to parse and process it. Because so much of the system runs on Spark, this was causing problems down the stack. To remedy this, we've replaced datetime.min with datetime.datetime('1900-01-01 00:00:00') for unspecified start times on Training Sets. (@sergioferragut , @Ben-Epstein )
