Allow callers to reset the git config cache

If commands modify the git config too rapidly we might not notice
the .git/config file has been modified, as they could run in the
same filesystem timestamp window and thus not cause a change on
the config's mtime.  This can cause repo to miss re-reading the
config file after running a command.

Allowing the cache to be flushed forces us to re-read the config.
