Extend type awareness with DataTypeIDs

[Zhaars]

Extending functionality of TA - added ability to directly specify data_type_db_identifier in encryptor config. Backward compatibility is saved as data_type is mapped to DataTypeID in the encryptor config.

The idea is to have DataTypeEncoder interface implemented for each supported DB type which registers in DataTypeIDEncoders map. In such cases, we can achieve more flexibility by substituting/adding new DB types
