Current implementation for the sending of security check metrics sends individual results as soon as checks are performed.
This could be optimized so that checks done via an Executor are sent in a single batch. There might be special considerations required for the AsyncCheckExecutor.

Since we're changing the this implementation it is a good opportunity to align the sent JSON with a format that can be used to group the same type of checks done in other SDKs as discussed in https://issues.jboss.org/browse/AEROGEAR-2210.
