When a cert gets issued, store a note in Mongo

[paulproteus]

The note should include:

• dev vs. prod-ness
• hostname
• the intended certificate validity information, specifically today's start date, and the # of days that we claim this is to be used for
• the actual parameters we passed to the GlobalSign API for validity
• the actual certificate that we got back from GlobalSign
• the status of this request (in_progress vs. complete vs. failed (?)), perhaps calculated rather than stored via knowing the GlobalSign order number (means "requested"), and the presence of the certificate (means "complete")

This is now done (I confirmed by manually querying Mongo). Closing issue.

(UPDATE: Edited to improve clarity.)
