[FLINK-9805][rest] Catch JsonProcessingException in RestClient
## What is the purpose of the change
With this PR `RestClient#readRawResponse` catches all JSON-related
exceptions. The exact circumstances where a `non-JsonParseException` is thrown
isn't clearly defined, but one case when it can occur is when the input is
empty.
