+Enhancement: make frontend prefixes configurable
+
+We introduce three new environment variables and preconfigure them the following way:
+
+```
+REVA_FRONTEND_DATAGATEWAY_PREFIX="data"
+REVA_FRONTEND_OCDAV_PREFIX=""
+REVA_FRONTEND_OCS_PREFIX="ocs"
+```
+
+This restores the reva defaults that were changed upstream.
