Merge #13987: Report minfeefilter value in getpeerinfo rpc

5778bf95d9 Report minfeefilter value in getpeerinfo rpc (Anthony Towns)

Pull request description:

  Lowering the minimum relay fee is only useful when many nodes in the p2p network also lower the fee, so to make it easier to understand progress on that front, this includes the value of the minfeefilter in getpeerinfo, so you at least have visibility to what fees your neighbours are currently accepting.
