When a Raft API call such as `add_entry`, `set_configuration` or `modify_config` takes too long, we need to time-out. There was no way to abort these calls previously so we would do that by discarding the futures. Recently the APIs were extended with `abort_source` parameters. Use this. Also improve debuggability if the functions throw an exception type that we don't expect. Previously if they did, a cryptic assert would fail somewhere deep in the generator code, making the problem hard to debug. Also collect some statistics in the test about the number of successful and failed ops. I used it to manually check whether there was a difference in how often operations fail with using the out timeout method and the new timeout method (there doesn't seem to be any). * kbr/nemesis-abort-source: test: raft: randomized_nemesis_test: on timeout, abort calls instead of discarding them raft: server: translate semaphore_aborted to request_aborted test: raft: logical_timer: add abortable version of `sleep_until` test: raft: randomized_nemesis_test: collect statistics on successful and failed ops
