Add README, PV, and PVC files to ci tests

ci_tests/README.md

+# Continuous Integration Tests
+
+This directory contains the necessary configuration to create and run tests
+during the CI "test" stage to do basic sanity checking of the installed
+components.
+
+These tests expect to be run in the "geosphere-ci-tests" namespace on a
+Kubernetes cluster, but this is configurable in the root `.gitlab-ci.yml`
+configuration file (see `TESTS_NAMESPACE`).
+
+## Administrative Setup
+
+These tests depend on input test data being present on the cluster. The exact
+path is in `cadu-pv.yaml`. Once the PeristentVolume and PersistentVolumeClaim
+are created, the input data will be fed to the test CSPP Geo GRB container.
+
+```bash
+kubectl -n geosphere-ci-tests create cadu-pv.yaml
+kubectl -n geosphere-ci-tests create cadu-pvc.yaml
+```
