Refactor Apex benchmark tests

Apex performance tests are refactored and reorganised
to be all in the one place and to be coherent.

A test REST server that can generate events in batches
is introduced and this can be configured to respond to REST
calls from Apex with various batch sizes that can be varied
for performance tests.

Actual performance tests are added for the various executors
in Apex.
