- Rename memory_monitor threshold key from 'percent' to 'memory_percent'
so it matches exactly rather than relying on suffix stripping, which was
causing swap_percent to be evaluated against the memory threshold
- Add swap_percent default thresholds (warning: 40%, critical: 75%)
- Add zfs_monitor pool capacity default thresholds (warning: 80%, critical: 90%)
