-// TickQuiesced advances the internal logical clock by a single tick without
-// performing any other state machine processing. It allows the caller to avoid
-// periodic heartbeats and elections when all of the peers in a Raft group are
-// known to be at the same state. Expected usage is to periodically invoke Tick
-// or TickQuiesced depending on whether the group is "active" or "quiesced".

-// WARNING: Be very careful about using this method as it subverts the Raft
-// state machine. You should probably be using Tick instead.

-// DEPRECATED: This method will be removed in a future release.
