v5.1

Fixes a bug that would cause the config not to be rebuilt if a configmap was simply deleted.

v5.0: Merge pull request #14 from Nordstrom/v3

New 5.0 version, no breaking changes. Some work to reduce churn, added an event recorder, configmaps will get events if keys are successfully loaded or not. Brought up to spec with the current kubernetes sample controller. If it finds two RuleGroup(s) with the same name it will automatically salt the name of the duplicate in the final configmap.

Allow flexitiblity in configmap value rule format.

Allows for configmap rules to be in the form of []Rules, RuleGroup, or RuleGroups as detailed in github.com/prometheus/prometheus/pkg/rulefmt
