[Feature]:Allow Posting multiple stream locations in single request

[Theresa5683]

Describe the bug

Is it the intent of the post stream-locations endpoint to allow multiple stream locations? I can only get one stream-location at a time to work.

Expected behavior

I thought that when I posted three stream-locations, that it would post all three. However, I can only do them individually. Not sure if I've got the formatting incorrect or if it just doesn't accept multiples.

To Reproduce

1. Go to CDA test swagger, post streamLocations
2. Select fail-if-exists=false
3. Put more than one gage in the request body. This is what I used:

[
  {
    "stream-location-node": {
      "id": {
        "office-id": "SWT",
        "name": "DIEB"
      },
      "stream-node": {
        "stream-id": {
          "office-id": "SWT",
          "name": "Saline_R"
        },
        "station": 53,
        "station-units": "mi"
      }
    },
    "area-units": "mile2",
    "stage-units": "ft"
  },
  {
    "stream-location-node": {
      "id": {
        "office-id": "SWT",
        "name": "DIES"
      },
      "stream-node": {
        "stream-id": {
          "office-id": "SWT",
          "name": "Saline_R"
        },
        "station": 48,
        "station-units": "mi"
      }
    },
    "area-units": "mile2",
    "stage-units": "ft"
  },
  {
    "stream-location-node": {
      "id": {
        "office-id": "SWT",
        "name": "LOCK"
      },
      "stream-node": {
        "stream-id": {
          "office-id": "SWT",
          "name": "Saline_R"
        },
        "station": 31,
        "station-units": "mi"
      }
    },
    "area-units": "mile2",
    "stage-units": "ft"
  }
]

Additional context

at this time all endpoints only explicitly take 1 "object"... though I can definitely see how one would look at the plural name and think otherwise.

There have been some discussions on allowing lists, and it wouldn't be super difficult to implement on the current endpoints.

Okay, thank you for letting me know!
