Locus Rest API Endpoint to Get All Locus fora given association

[sprintell]

As developer I want an api endpoint such that that when I send a GET request to the URL, hateoas compliant, paginated list of all loci of a given Locus in the database is returned in JSON Format

This is a new endpoint, this is required to ensure scalability, it was previously embedded in the Association endpoint, but now a child object accessible from within the Association payload as a link on the URL

{
   "haplotypeSnpCount":null,
   "description":"Single variant",
   "strongestRiskAlleles":[
    {
        "riskAlleleName":"rs9497975-?",
        "riskFrequency":null,
        "genomeWide":null,
        "limitedList":null
    }
   ],
   "authorReportedGenes":[
    {
        "geneName":"intergenic",
        "entrezGeneIds":[

        ],
        "ensemblGeneIds":[

        ]
    }
   ]
}

Management Rules

• Rule 1: Endpoint - /v1/associations/{associationId}/loci
• Rule 2: HTTP Request Method - GET
• Rule 3: Endpoint should accept associationId as a path variable
• Rule 4: Endpoint should return full attributes of the loci
• Rule 5: Endpoint should be accessible to all

Acceptance Criteria:

• Given a correct associationId, when the front end sends a GET request to the endpoint
• List of corresponding loci data is returned in JSON Format
• Given a wrong associationId, when a GET request is sent to the endpoint
• Properly described Resource not found exception error should be returned as JSON payload
