resets the timeout
The implementation should provide sensible default timeouts, but the caller can opt to provide a delay. For example, in the occasion of an endpoint failure or a user interaction, we may want to schedule at a sooner (or event immediate) time
In the event of a timeout, the call-back can elect to schedule another timeout event at the given delay.
the delay to use when set, otherwise None
true if a scheduled timeout has been cancelled by invoking, false if either it couldn't be cancelled or a task wasn't scheduled in the first place
debug info regarding the time state
Timers are tricky, as they need to be given to a ClusterProtocol, but the cluster protocol needs to reference nodes, which the timers in turn need to have a reference to.
Because of this circular reference, we make an 'initializable' timer, which is a valid RaftTimer, but resets won't take affect until it has been initialized.
