-At the beginning of each block, we update the signing info for each validator and check if they've dipped below the liveness threshold over the tracked window.  If so, they will be slashed by `LivenessSlashAmount` and will be Jailed for `LivenessJailPeriod`.  Liveness slashes do NOT lead to a tombstombing.
