feat: experiment library schema changes, ingestion report with errors, json schema warnings

[v-rocheleau]

Ingestion report

The ingestion endpoint now returns an "ingestion report" in the response's JSON, with shape:

{
  "success": true,
  "errors": [],
  "warnings": []
}

Where,

• success indicates if the ingestion was successful (now http status 201, was 204)
• errors lists the errors that were caught during ingestion, causing a failed ingestion
• warnings lists custom warnings related to schema changes.

Ingestion WDLs

• Workflow files for experiments and phenopackets ingestion now store the ingestion report JSON in the run directory
• The ingestion report is now an output of the workflows

Schema Changes

Katsu can now keep track of JSON-schema modifications in a release.
The schema changes objects are used to perform data migrations in Django, they also allow the ingestion view to compile warnings if deprecated properties are found in the submitted data.

EXPERIMENT_SCHEMA_CHANGES = {
    "4.1.0": {
        "properties": {
            "library_strategy": [
                    ("WES", "WXS"),
                    ("Other", "OTHER"),
            ],
            "library_selection": [
                    ("Random", "RANDOM"),
                    ("Random PCR", "RANDOM PCR"),
                    ("Exome capture", "Hybrid Selection"),
                    ("Other", "other"),
            ]
        }
    }
}

EBI experiment schema

• XSD experiment file taken from EBI's schema database: http://ftp.ebi.ac.uk/pub/databases/ena/doc/xsd/sra_1_5/
• experiment's library_strategy and library_selection values are read from the file and used in the schema
• data migration to convert 'WES' -> 'WXS', etc

some notes

++ if we don't want to bother preserving backwards compatibility, we could just save this for katsu 5.0.0 instead
