Bulk update of references to the group.

Add or remove references to the group, leaving references not listed in the request body unchanged.

For example, to link stream_1 to the group my_group and unlink stream_2 from it, issue the following PATCH request to /groups/my_group/references/streams:

{
  "addReferences": [
    "stream_1"
  ],
  "removeReferences": [
    "stream_2"
  ]
}

All other streams will remain linked or unlinked from my_group as they were before the request.
