DATAREDIS-593 - Use Enum.name() to represent enum values.

We now serialize Enum values using their name (Enum.name()) instead of using their string representation (Enum.toString()). toString can be customized in Enums to no longer report their name but a different value. A customized value cannot be used to reinstantiate the Enum value, only its name.

This change affects serialization and will only affect new/updated values. Stored values with a customized toString representation still can't be deserialized until they were updated in Redis.
