This was kept this way to preserve legacy behavior, but I think changing the behavior will be less of a problem than what the current behavior causes. The policy is used for reconnections (for example, reconnecting control connection). If reconnect policy finishes generation (it will do so after 64 attempts before my change), then the reconnector finish and the driver won't attempt reconnection anymore. This would be a terrible situation.
This better conveys what this is: not a timeut duration from config, but how much of this timeout is left right now.

@Lorak-mmk , you need to fix tests that assert this exception |
The timeout argument in `wait` tells how much we need to wait taking into consideration that we already waited for some other futures. The total wait time that this future had available to complete is different: it includes time we spent waiting for other futures. This created confusing hearbeat messages, that could even show negative wait times. I fixed it by putting both timeouts in the error message. The `timeout` parameter of `OperationTimedOut` I changed to the original timeout because I think it is more useful and relevant here.

When looking into #295 and https://scylladb.atlassian.net/browse/SCYLLADB-1251 I found some minor issues that this PR fixes.
Connection heartbeat timeout after -56.143085956573486 seconds, last_host=127.0.16.3:19042. This is because they usedtimeoutargument passed towait, which is not the whole timeout duration, but the duration LEFT after waiting for other futures.Pre-review checklist
