Remove Donor/Specimen/Sample - from Analysis Entity Classes

[joneubank]

This ticket is contributing to the epic: #863

Summary

Update Analysis data classes in Song to remove Donor, Specimen, and Sample.

Since these classes are used throughout the code base this will break many other classes, so references to these properties should be removed and cleaned up so that the code base can still build without these properties.

Details

The classes that need to be updated are:

1. bio.overture.song.core.model.Analysis
2. bio.overture.song.server.model.analysis.Analysis
3. bio.overture.song.server.model.analysis.DataEntity

From these classes we need to remove all hardcoded references to donor, specimen, and sample classes, or IDs representing these entities.

Additional context

As part of this ticket, we don't need to remove the classes representing the Donor, Specimen, or Sample entities. We will remove all uses of these classes and then remove the code for these classes and their correspondign repositories once analyses are stable without them.
