Updating Incident Reports

[BenWilson-Mozilla]

I think this issue is somewhat related to mozilla/www.ccadb.org#99. Currently, MRSP section 2.4 says
"CA operators MUST regularly update the Incident Report until the corresponding bug is marked as resolved". The recent CCADB proposal for incident reports states, "The full incident report must be posted within two weeks of the incident. Once the report is posted, CA Owners should respond promptly to questions that are asked, and in no circumstances should a question linger without a response for more than one week, even if the response is only to acknowledge the question and provide a later date when an answer will be delivered." https://github.com/mozilla/www.ccadb.org/compare/2be8d48..41e1892. Thus, this phrase in section 2.4 of the MDSP will likely need to be modified to be consistent with the CCADB Policy.
