feat: Update NMS and Security Monitoring mentions within NIM docset

[ADubhlaoich]

Proposed changes

This commit removes mentions of NGINX Management Suite from NGINX Instance Manager documentation, and also clarifies mentions of Security Monitoring as a module. In many cases, due to noun usage, it read as its own separate product, instead of a component.

The frontmatter metadata has also been brought to contemporary standards for all files affected. There are more instances of NMS being mentioned across other products, but they will be addressed as their own discrete PRs for those products, keeping the scope of this one smaller.

Coming in NIM 2.19, Sec Mon will be a built-in feature of NIM and not a standalone module.

[travisamartin]

I'd avoid calling Sec Mon a module -- it'll be a feature of NIM 2.19 (automatically installed w/ NIM).

[travisamartin]

Since Sec Mon is installed w/ NIM 2.19, this guide will be removed.

That update is in the docs-1604-decouple-security-monitoring branch, out for review. You might want to rebase to that branch. I also removed the Sec Mon RNs.

Here's the related PR: #86

Suggested change

As demonstrated in Figure 1, Instance Manager lets you manage security configurations for NGINX App Protect WAF. You can define security policies, upload attack signatures and threat campaign packages, and publish common configurations out to your NGINX App Protect WAF instances. Instance Manager can compile the security configuration into a bundle before pushing the configuration to the NGINX App Protect WAF data plane instances. The Security Monitoring module provides data visualization for NGINX App Protect, so you can monitor, analyze, and refine your policies.
