Show Inactive Nodes

[PeterYurkovich]

Resolves #39

Background

Before release-0.1 nodes on the graph were hidden if they were unable to link to an appropriate location for some reason. However this causes some charts to be split. ie. a netflow node connects 2 halves of a graph, but the netflow plugin isn't enabled. However, these nodes may link to inaccessible places or have no links at all.

Solution

This PR looks to re-add the nodes to the graph, differentiate them from valid nodes and give a brief description of the reason they are disabled. It gives 3 preset reasons for the nodes being unavailable

• Logging Plugin Unavailable
• Netflow Plugin Unavailable
• Korrel8r Query Unable to be Converted to Link

It also puts a length limit on error messages to prevent overflow of the error messages.

Visualization

[fkargbo]

I checked out some PatternFly design guidelines and found an example we could use in addition to what you already have.

For disabled nodes, we could apply some opacity to the visual styling as shown in the screenshot.

Here's a link to the document for you to refer to. Let me know what you think. Thanks!

@fkargbo Demo of the updated UI. After looking at the patternfly css variables I saw that 30% opacity was used in other places so thats what I've used here.
