v1.0.4

v1.0.4 re-adds per-consumer metric reporting

v1.0.2 brings a few bug fixes

* The management libraries should now work on Flex. Note that you must
  use ControlFilter instead of GoogleAppEngineControlFilter on Flex.
* Attempts are made to handle the incompatible error handling from the
  new dev server code (such as internal exceptions for not being able to
  resolve the metadata service URL)
* Removed an unnecessary gRPC dependency, which cuts down on the number
  of dependencies by a significant amount.
