Previously the two values were the same; this caused us
to always exceed the timeout limit ACK_REQUEUE_EVERY_SECONDS_MAX
which results in various code paths never being traversed
due to premature timeout exceptions.
Also apply min/max values to kombu_reconnect_delay so it doesn't
exceed ACK_REQUEUE_EVERY_SECONDS_MAX and break things again.
