- The notifier was never checking if it should shutdown if there were always at least one notification to send
- After a failure, the notifier is supposed to back-off, but when Clair is stopping, the backoff was interrupted immediately and did not retry. Instead it selected a new notification to send (most likely: the same one) and looped quickly/weirdly.
Clair will now use a YAML configuration file instead of command line
arguments as the number of parameters grows.
Also, Clair now exposes a Boot() func that allows everyone to easily
create their own project and load dynamically their own fetchers/updaters.
