Sochain cryptocurrency sensor (#11335)

* add required files

* add sochain sensor

* add missing schema

* end first sentence with a period to make travis happy

* upgrade to python-sochain-api 0.0.2 and use asyncio

* add missing _LOGGER and fix long line

* move object setup to async_setup_platform

* rename chainSo variable to chainso
