* ES index written must match reader side

Change this line https://github.com/lyft/amundsendatabuilder/blob/v1.0.11/example/scripts/sample_data_loader.py#L177 to match the current hardcoded value in the search service at 
https://github.com/lyft/amundsensearchlibrary/blob/v1.0.0_4/search_service/config.py#L23. This means it’s backwards compatible with existing search service Docker containers etc.

* Bump package version to 1.0.12
