Title: Extend RequestProcessor to be able to block item retrieval

Extends RequestProcessor to be able to block an item retrieve request.

For example a request processor could make a request to Insight to check if the item to be retrieved has any vulnerabilities.
Another example an blacklist could stop retrieval on an artifact that is know to have problems.
