Report API issues to Digicert

[ronaldtse]

Here the issues we encountered:

• Certificate generation process does not directly link the reissue request to the resulting certificate. Workaround: we use certificate issue time to correlate the issuance
• Request endpoint often contains stale cached certificate objects (i.e. an embedded certificate object that has status “needs_approval” but the request is “issued”)

@abunashir could you help add additional issues that I missed? Thanks!

@ronaldtse: I think we've already reported this one, do these issues still persist? Do we need to keep this issue open?
