What functionality?

Done.

RefreshTokenStore - Chromium style has the interface with a "plain" name and
implementations with longer names, e.g. RefreshTokenStoreOnDisk, etc.

Done.

This name assumes an on-disk implementation, but this is an interface so I think
you want just Get/SetRefreshToken or Store/FetchRefreshToken.

Done.

Suggest making this a static OnDisk() method in RefreshTokenStore, i.e.
RefreshTokenStore::OnDisk()

Done.
