Pull request description:

  This lets users pick their own fees when using `sendtoaddress`/`sendmany` if they prefer this over the estimators.

ACKs for top commit:
  Sjors:
    re-utACK 25dac9fa65: rebased, more fancy C++,
  jonatack:
    ACK 25dac9fa65 I think this should be merged after all this time, even though it looks to me like there are needed follow-ups, fixes and test coverage to be added (see further down), which I don't mind helping out with, if wanted.
  fjahr:
    Code review ACK 25dac9fa65

Updated or changed RPC
----------------------
The `bumpfee`, `fundrawtransaction`, `sendmany`, `sendtoaddress`, and `walletcreatefundedpsbt`
RPC commands have been updated to include two new fee estimation methods "BTC/kB" and "sat/B".
The target is the fee expressed explicitly in the given form. Note that use of this feature
will trigger BIP 125 (replace-by-fee) opt-in.
In addition, the `estimate_mode` parameter is now case insensitive for all of the above RPC commands.
The `bumpfee` command now uses `conf_target` rather than `confTarget` in the options.
