[chronik] Add an integration test for the blockchain_info endpoint in bitcoinsuite-chronik-client
Summary:
Depends on D17595 - this diff uses features from D17595 files test_runner.rs and handler.rs.
Use the bitcoinsuite-chronik-client to return the tip height and tip hash length, thus we can compare with the python bitcoin tests and assert if they are equal.
Test Plan:
Please set BUILD_DIR env to export BUILD_DIR="/path/to/build_dir
UNIX: ./contrib/teamcity/build-configurations.py build-bitcoinsuite-chronik-client
cd modules/bitcoinsuite-chronik-client && cargo test
