[#2208] engine: Log time-consuming shard operations

Browse source 
Currently the only way to tell whether `evacuate/set-mode` is finished
is to set a very big timeout and _hope_ that the operation will finish.
In this commit we add INFO logs for such operations which should
simplify the life of an administrator.
