This wasn't quite what I meant.

I think the name should still be passed to the API, but the other params should
be in the registry referenced by the enum.

(And the enum name should be more generic - e.g. RAPPOR_URL rather than
RAPPOR_HOMEPAGE).

To avoid having to refactor things too much, maybe you can still keep the name
in RapporParameters, but have an empty name for all of these pre-defined ones
and have a call to RapporService copy the params over and fill the name.

Split name and parameters.  PTAL.
