[Tarantool-patches] [PATCH vshard 6/6] router: update master using a hint from storage

[Vladislav Shpilevoy]

>   - After changes in previous patch I think it could be better to use "master_search_wakeup" instead of master_search_fiber:wakeup()

Yes, I forgot to update this commit. Done now:

>   - Should we document somehow `update_master` method for replicaset object? Or maybe it even shouldn't be a part of public API?

Nope. It is a private method. If something is not documented on the
site, it is private. I couldn't come up with a better scheme and yet
not harm vshard's own code readability.
