Exclude some targets from `tuist inspect redundant-imports`

Hello :wave:

I have some helpers to define my feature modules, and those helpers do some magic to simplify the manifest definition, for example, any dependency of the implementation and interface target is also added to the related test target or to the demo app.
This of course causes some warnings when I run tuist inspect redundant-imports because the dependency is not always needed.

What do you think of adding an inspectRedundantImport boolean (default true) to TargetMetadata?
