Get customer AdjunctQueue

[donaldgray]

Implement API endpoint GET /customers/{customer}/adjunctQueue. This is the equivalent of /customers/{customer}/queue and works in an identical way, with the difference being this returns a CustomerAdjunctQueue.

See https://dlcs.github.io/public-docs/api-doc/queues/#adjunct-queue

Example response:

{
    "@context": "https://dlcs.github.io/vocab/context/future.json",
    "@id": "https://api.dlcs.example/customers/2/adjunctQueue",
    "@type": "vocab:CustomerAdjunctQueue",
    "size": 170,
    "batchesWaiting": 0,
    "adjunctsWaiting": 0,
    "batches": "https://api.dlcs.example/customers/2/adjunctQueue/batches",
    "active": "https://api.dlcs.example/customers/2/adjunctQueue/active",
    "recent": "https://api.dlcs.example/customers/2/adjunctQueue/recent"
}

• batches, active and recent links show correct links (note that these will 404 until implemented)
• size - Number of total adjuncts in your queue, across all batches. This number decreases as the platform processes your adjuncts.
• batchesWaiting - Number of adjunct batches that are waiting to be processed. These are batches that have been submitted but are not yet the platform has not yet started working on them.
• adjunctsWaiting - Number of adjuncts waiting to be processed. These are adjuncts that have been submitted but the platform has not yet started working on them. This differs from in that it excludes adjuncts currently being processed.
