samples: modules: thrift: add samples for thrift module

Here we add a client and server samples for the basic
"hello" service.

These samples are designed to be run by either Zephyr or
the host machine, interchangeably.

Additionally, there is a python version of the client
to demonstrate Thrift's cross-language capabilities.

This code was merged from the following repository
at the commit specified below, with minor formatting
and coding-style modifications.
