What is the use case for rietveld.extra_cc? I'm guessing its to setup a CC_LIST
specific to the current issue which you want to persist for the duration of the
issue. In that case, you'd want to store extra_cc in the branch config. See
_IssueSetting() for an example.

Here, we are storing extra_cc as a repo config which persists across branches.
Not sure why someone would want to do that.
