Optimize tablets in regards of the memory allocations: 1. `fieldalignment` 2. `type TabletInfoList []*TabletInfo` -> `type TabletInfoList []TabletInfo` 3. Remove keyspaceName and tableName from TabletInfo 4. Switch ReplicaInfo.hostID to binary...
Instead of storing all the tablets in the list, store them in the `map[ks+table]`
