Since we will be continuously deprecating out-of-date features as we drop support for server versions, we should look in a unifying approach as to how we emit deprecation notices.

Some things to consider:

• util.deprecate is available in all versions of Node that we support, and has some nifty features. It only works by wrapping a function, so we need to figure out how to incorporate this in to other deprecation notices
• Should this be integrated with options-management NODE-1256?
• Should we be logging to log files for deprecation warnings as well?
