/**
 * bumpfee "txid" ( options )
 *
 * Bumps the fee of an opt-in-RBF transaction T, replacing it with a new transaction B.
 * An opt-in RBF transaction with the given txid must be in the wallet.
 * The command will pay the additional fee by reducing change outputs or adding inputs when necessary.
 * It may add a new change output if one does not already exist.
 * All inputs in the original transaction will be included in the replacement transaction.
 * The command will fail if the wallet or mempool contains a transaction that spends one of T's outputs.
 * By default, the new fee will be calculated automatically using the estimatesmartfee RPC.
 * The user can specify a confirmation target for estimatesmartfee.
 * Alternatively, the user can specify a fee rate in sat/vB for the new transaction.
 * At a minimum, the new fee rate must be high enough to pay an additional new relay fee (incrementalfee
 * returned by getnetworkinfo) to enter the node's mempool.
 * * WARNING: before version 0.21, fee_rate was in BTC/kvB. As of 0.21, fee_rate is in sat/vB. *
