Update python extended example

[Zhaars]

As part of acra-engineering demo Type Awareness feature we need to extend python examples to support it.

Since python examples from acra are used inside acra-engendering demo, this PR is part of acra-eng demo modification.

This PR contains little extends of encryptor configs with new data_type fields. Important part is adding one more schema inside py files. These are needed to construct table inside DB(with raw fields) and another for making queries (with defined type)
