user auth token load tests using k6.io

devenv/docker/loadtest/README.md

+# Grafana load test
+
+Runs load tests and checks using [k6](https://k6.io/).
+
+## Prerequisites
+
+Docker
+
+## Run
+
+Run load test for 15 minutes:
+
+```bash
+$ ./run.sh
+```
+
+Run load test for custom duration:
+
+```bash
+$ ./run.sh -d 10s
+```
+
+Example output:
+
+```bash
