Thomas Draebing eb4e6ea191 Use object store to store chunks created by Loki
The chunks created by Loki were stored in a persistent volume. This
does not scale well, since volumes cannot easily be resized in
Kubernetes. Also, at least the ext4-filesystem had issues, when large
numbers of logs were saved. These issues are due to the dir_index as
discussed in [1].

An object store provides a more scalable and cheaper solution. Loki
supports S3 as an object storage and also other object stores that
understand the S3 API like Ceph or OpenStack Swift.

Thomas Draebing be862d863e Move internal project to open source
This change adds the current status of a project that aims to create
a simple monitoring setup to monitor Gerrit servers, which was developed
internally at SAP.

The project provides an opinionated and basic configuration for helm
charts that can be used to install Loki, Prometheus and Grafana on a
Kubernetes cluster. Scripts to easily apply the configuration and
install the whole setup are provided as well.
