Roy Lee 811741d099 [lbry] fees: port estimatesmartfee from DCRD
1. logger
2. blockheight: int64 -> int32
3. dcrutil -> lbcutl
4. MaxConfirimation: 42
5. MinBucketFee: mempool.MinRelayFee (default 1000)
6. BucketFee Spacing: 1.1 -> 1.05

Note:
  DCRD implementation of estimatesmartfee is based on bitcoin core 0.14
  Lbrycrd (0.17) includes the updates of bitcoin core 0.15.
  They are slightly different, but shouldn't matter much.
