Filters entities in relational graph of report knowledge

[I-Iugo]

Problem to Solve

For a better reading it would be good to be able to have filters on the entities present in the graph. Maybe link to #41 issue

Current Workaround

None

Proposed Solution

The solution would be to set up filters by entity types: Malware, Intrusion-set, ...

If we filter an entity B included between 2 entities A and C then we could imagine having a link of inference in the form of a dotted line.

This feature would be great.
Some times the graphs are simply impossible to read (e.g. when there are tons of indicators linked to a malware, for example)
