Merge bitcoin/bitcoin#22722: rpc: update estimatesmartfee to return max of CBlockPolicyEstimator::estimateSmartFee, mempoolMinFee and minRelayTxFee
ea31caf6b4c182c6f10f136548f84e603800511c update estimatesmartfee rpc to return max of estimateSmartFee, mempoolMinFee and minRelayTxFee. (pranabp-bit)
Pull request description:
This PR is in response to the issue [#19699](https://github.com/bitcoin/bitcoin/issues/19699).
Based on the discussion in the comments of PR [#22673](https://github.com/bitcoin/bitcoin/pull/22673) changes have been made in the `estimatesmartfee` itself such that it takes into account `mempoolMinFee` and `relayMinFee` . Hence it provides a fee estimate that is most likely to be paid by the user in an actual transaction, preventing issues such as [#16072](https://github.com/bitcoin/bitcoin/issues/16072).
The test file test/functional/feature_fee_estimation.py has also been updated to check this functionality.
