Remove Threat Monitoring page

Why are we doing this work

Container Network Security and Container Host Security have been deprecated and will be removed in %15.0. As part of this removal, will be removing the entire Threat Monitoring page at Security & Compliance > Threat Monitoring, as well as any associated backend code. The alerts tab may be re-implemented again in the future, so its removal should be contained in an individual commit that can be reverted.
