      This is for possible format changes, like upgrading SHA1 to SHA256.

      Existing format:

      logicalTime: {
          clusterTime: <Timestamp>,
          signature: <SHA1 hash of clusterTime as BinData>
      }
      

      New format:

      logicalTime: {
          clusterTime: <Timestamp>,
          signature: { version: <int>, hash: <SHA1 hash of clusterTime as BinData> }
      }
