   add coin selection strategy option to the following on-chain RPC calls

+* Previously when callng `SendCoins`, `SendMany`, `OpenChannel` and
+  `CloseChannel` for coop close, it is allowed to specify both an empty
+  `SatPerVbyte` and `TargetConf`, and a default conf target of 6 will be used.

+* `BumpFee` has been updated to take advantage of the [new budget-based
+  sweeper](https://github.com/lightningnetwork/lnd/pull/8667). The param
+  `force` has been deprecated and replaced with a new param `immediate`, and a
+  new param `budget` is added to allow specifying max fees when sweeping
+  outputs. In addition, `PendingSweep` has added new fields `immediate`,
+  `budget`, and `deadline_height`, the fields `force`, `requested_conf_target`,
+  and `next_broadcast_height` are deprecated.
