* Remove SetWithTTL from WriteBatch as part of New EntryAPIs. As we have removed SetWith functions from Txn struct. We can do same for WriteBatch. Anyone can create Entry using new Entry APIs and call SetEntry on WriteBatch. * Change WriteBatch Set method to have same syntax as Txn.Set * Fix DOCs for Entry APIs
