Update release notes/wiki upgrade doc to better document stopping/starting server during upgrade

Description

As a Repose user, I want to have clear instructions around upgrades for when and how to stop and start the Repose server. DEB and RPM packages will not automatically stop or start the server.

This story originated from comments in https://github.com/rackerlabs/repose/pull/1186. Decision was made by PM and team not to attempt to automatically stop and start the server.

See comment for what documentation needs to be updated.
