RetrievalContext

This RetrievalContext holds all the necessary information that is needed to validate a validatable object. According to the requirements in the specification we probably need access to the following information:

• The (parsed) JSON containing the provider metadata; see RetrievalContext.json

• The filename of the JSON

• The URL where it was downloaded (both to check whether a TLP:WHITE is accessible and/or a TLP:RED is not accessible and whether TLS is used); see RetrievalContext.httpResponse

• The HTTP headers used in the HTTP communication to check for redirects; or the complete HTTP request; see RetrievalContext.httpResponse)
