ApiXmlDocWriter: add more search name spaces to find APIs

Whenever a new API command is added to CloudStack, if developers are not using
the recommended namespace of org.apache.cloudstack.api.* they should add their
custom namespace/package here. ApiXmlDocWriter uses ReflectUtils to find APIs
within these packages (which must be also available in cloud-client).
