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.
