Commit Message

feat(iota-core, consensus): Misbehavior report rate limit (#10189)

# Description of change

- Adds information about the last submitted report (sequence number and
summary) to `Scorer`.
- Rate-limit report submission: reports are only sent when all three
conditions are met:
1. Metrics have changed since the last report (according to report
summary)
    2. At least 1000 checkpoints have passed since the last report
3. The current checkpoint is at most 100 behind the highest verified
checkpoint (avoids sending reports during resync)
- Forces a report to be sent when the epoch is coming to an end:
1. A report is additionally sent when `checkpoint_timestamp >=
next_reconfiguration_timestamp_ms - 2000`. This condition should be
sufficient so that most authorities can have their reports included
before the epoch closes.

## How the change has been tested

- [x] Basic tests (linting, compilation, formatting, unit/integration
tests)
- [ ] Patch-specific tests (correctness, functionality coverage)
- [ ] I have added tests that prove my fix is effective or that my
feature works
- [x] I have checked that new and existing unit tests pass locally with
my changes
