NEST Data source API

The NEST Data source API provides a way for NEST to interact with several data sources. Each data source should implement the DataSource trait and expose the DataSourceApi to enable NEST to interact with it. The data source API is built on top of the actix-web framework and uses the actix-web-httpauth middleware for authentication, with a simple authentication token. The API can either be run as a standalone server or included in a larger actix-web application.

Under the hood, the data source API uses the paas-client to pseudonymize data between NEST and the data source.
