Build the foundation for API v2 development

Context

The v2 API version will use the following unified schemas SamplesAnalysesReport and SamplesAnalysis. We need to prepare the framework to be able to handle requests to those types of records.

Backward compatibility The system will not provide backward compatibility for records created using different versions of the API

Acceptance criteria

1. The application supports both versions v1 & v2;
2. The /docs endpoints return information both for v1 & v2
3. The v1 must be supported until its deprecation date
4. Placeholders for the samplesanalysesreport & samplesanalysis enpdoints created
