Promtail was configured to create labels for nearly every key in the
logs. This was done to support easier label-based querying. Loki
however is not optimized to work with labels having a high cardinality.
This led to failures in Loki, if it had to handle a high number of
logs. In addition, the high number of labels led to a huge number of
chunks being created, mostly just containing a single log entry,
making querying and storage very inefficient.
This change removes all custom made labels, except for the
gerrit_version label. Logs should rather be queried using the grep-
like syntax of LogQL for which Loki is optimized.

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.
