Add command that lists features that contain a specific bundle

Many times during integration of services I found conflicting bundles installed by dependent features. This command would help pinpoint the offending features, assisting in such tasks.

I will attach my implementation to this issue. Please comment.

The issue does not name any files, tests, or entry points, and no implementation is attached in the payload. First locate the existing Karaf feature-listing command and its tests, then define the command's input and output for finding features that contain a specified bundle; done means the command identifies the relevant dependent features and has coverage for the behavior.
