[HELIX-669] State transition cancellation implementaion
State transition takes a vital part of Helix managing clusters. There are
different reasons can cause state transition is not necessary, for example, the
node of partition running state transition is down. Thus state transition
cancellation would be a useful feature to have in Helix. It not only helps
cancel the state transition to avoid invalid state but also benefits for
reducing redundant state transitions.
