[BUG] retrieve-by-key requests all items for each key thats given

[JoernBerkefeld]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

if you pass in 2..n keys for all types that use super.retrieveREST() then it will not actually request that particular key from the server but instead request all and then filter the result set.

because we do run retrieve once per key, that means that we end up re-running the same request per key

Expected Behavior

for types that dont support filtering the request by key, we should only do one callout and filter for all given keys.

Steps To Reproduce
