time-dependent feature

  1. In addition to tokenid, we need to add a lifetime field to indicate the lifetime of the token.

  2. The field lifetime use the BlockNumber type to indicate maximum height it can survive.

  3. Use the on_finalize method to listen for block number updates and then automatically destroy expired tokens.
