Fix Scan Server Status Icon colors in 4.0.0 Monitor

[Amemeda]

This pr fixes a bug in the 4.0.0 Monitor where the Scan Server status icon in the Server drop-down does not display the correct status color. Added new logic to correctly determine the color of the Scan Server status icons:

Scan Server Status Icon should be:

• Green (OK) when responding servers = total servers (ex: 0/0 or 3/3)
• Yellow (WARN) when responding servers is nonzero AND < total servers (ex: 1/3)
• Red (ERROR) when responding servers = 0 AND total servers > 0 (ex: 0/3)

This pr closes #6576

OK Status:

_____________________________________________________________________________________________________________________

WARN Status:

---

**ERROR Status: **

I think there are some issues with this approach. This new code replaces the status the server sends with one recomputed from the counts which loses things the server already checks for (like WARN for servers that are not reporting metrics will now show green here). It also only fixes the scan servers circle in the drop down and does not properly affect the rolled up Servers circle which still uses the old status so it will stay red with 0 scan servers.

I think the only change we need is in getComponentStatus() in functions.js. Adding a new check "if status.hasServers is false AND the component type is scan server, return OK" since scan servers are optional. That would fix both status circles and the navbar.js changes can be reverted.

This introduces a problem for Scan Servers, In the case where there are no responding Scan Servers out of nonzero total, the icon should be red, but with that added logic it allows the icon to remain green. Is there a way for me to add to that condition to check the total scan servers?

It also stops the WARN status when scans servers is something like 1/3.

Looks good to me
