RFE: Return original input _id in getTotals request

[jiekang]

When you make a request to getTotals you submit an id to request for (for example https://trss.adoptium.net/api/getTotals?id=65a706d596a988006d0eed2b) and it returns a response like:

{
    "_id": {},
    "total": 854,
    "executed": 337,
    "passed": 322,
    "failed": 15,
    "disabled": 72,
    "skipped": 445
}

The _id field is intentionally omitted at the moment:

https://github.com/adoptium/aqa-test-tools/blob/faa3b1c82e93e11aef7fa04f8d15f454e7b9ee87/TestResultSummaryService/Database.js#L179

This issue is a request to return the original _id that was submitted. This is useful for further parsing of the data in different contexts as one can identify the source of the data from the data itself.

So for the above example, the preferred response would be:

{
    "_id": "65a706d596a988006d0eed2b",
    "total": 854,
    "executed": 337,
    "passed": 322,
    "failed": 15,
    "disabled": 72,
    "skipped": 445
}
