Add optional support for Yandex.Maps static API 

You could enable it via CMake option KEPKA_OPTION_USE_YANDEX_MAPS:
cmake -DKEPKA_OPTION_USE_YANDEX_MAPS=ON ..

It is used instead of Google Maps API for locations and on location click.
Sometimes Google Maps return no maps data. It is related with recent free
API usages count decrease from 750k requests to 28k (according to
https://habr.com/post/417715/).

The code on this commit will be cleaned up and rewritten using Maps API
string builders in next commit.
