+    Allow operators to use custom parameters with the ceilometer-upgrade
+    command. This is quite useful when using the dynamic pollster subsystem;
+    that sub-system provides flexibility to create and edit pollsters configs,
+    which affects gnocchi resource-type configurations. However, Ceilometer
+    uses default and hard-coded resource-type configurations; if one customizes
+    some of its default resource-types, he/she can get into trouble during
+    upgrades. Therefore, the only way to work around it is to use the
+    "--skip-gnocchi-resource-types" flag. This release introduces a method for
+    operators to execute such customization, and many others if needed.
