Fix Monitoring Service startup

The Monitoring Service was not starting due to some missing CTS Guice
dependencies.

This patch exposes `Debug`, `CTSOperationsMonitoringStore` and
`CTSReaperMonitoringStore` instances so they are available in the
impacted classes from the package `org.forgerock.openam.monitoring.cts`.

Additionally, unused imports have been removed and an incorrect comment
block style was updated to improve clarity.
