It allows nodes to protect themselves from being flooded with HTLCs.

- Improved web interface.
This release updates circuitbreaker to v0.5.0, which adds functionality to track granular HTLC forwarding information that is not saved by LND. This detailed information about HTLC forwards is also valuable for node operators looking to gain a more detailed understanding of their forwarding flow.
- Edit limits for multiple nodes in one operation.
- Added BLOCKED mode to completely block traffic from a peer.
Specifically, it will persist timestamped forwarding history records for successful and failed HTLCs (LND only saves successful forwards, and does not keep timestamps). By default, circuitbreaker will only store 100,000 records so the maximum amount of space that these records will take is approximately 14MB. This value can be changed using the `--fwdhistorylimit` flag, which allows zero values to disable the feature completely.
- Fixed bug where Circuit Breaker wouldn't restart after a failure.
This feature was developed as part of the ongoing protocol work to research mitigation of channel jamming attacks against the network (https://lists.linuxfoundation.org/pipermail/lightning-dev/2023-August/004034.html). Volunteers interested in contributing to this research through running *local-only* analysis of the data circuitbreaker collects can express interest at https://docs.google.com/forms/d/e/1FAIpQLScm2xs4hNsrkI8UCBS4aTdO03YrmWT2X0-j6zXWpkZ7keKiUw/viewform?usp=sf_link or contact carla@chaincode.com for details.
