Fix Monitoring Service startup

[fyrbach]

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.
