Additional Partition Metrics & Bugfixes

• Additional partition metrics (partition count and cleanup policy)
• Offset commit counter for each group:topic:partition combination to get commit rate
• Added sample grafana dashboard for this version
• Separate readiness & liveness check so that pods may only be marked as ready once the offsets consumer topic has been completely consumed and therefore up to date metrics can be exported

Only expose metrics if offets topic has been consumed

Prometheus metrics will only be exposed after the consumer offsets topic lag has been caught up by all partition consumers. This way we can ensure that only accurate group lags (instead of outdated) will be exported.
