About Aggregator

Does service discovery via kubernetes api and calls /__/about for each service that exposes the endpoint. Service are filtered based on labels(about=true).
For each service this information is pushed to several exporters:

• HTTP exporter - exposes list of services which expose /__/about
• Confluence exporter - pushes the list of services which expose /__/about to confluence
