Add display parameter to getScanResults (API)

[DanielKrasny]

The actual output of /api/v1/getScanResults is an object, where value contains next object with test result properties. These properties contain a name key, which value is identical to name of superior's object key.

Example (simplified for clarity):

{
    "content-security-policy": {
        "name": "content-security-policy"
    }
}

For my use case, I found an alternative keeping only the value objects and passing them into array. The name remained only in the properties object. Of course, I don't want to break current code, so this option is available as an optional parameter.

Example (simplified for clarity):

[
    {
        "name": "content-security-policy"
    }
]

The initiative comes from no availability to iterate through object keys in programming language that I currently use.
