[Tarantool-patches] [PATCH vshard 00/11] VShard Map-Reduce, part 2: Ref, Sched, Map

[Vladislav Shpilevoy]

The patchset is a second part of the series introducing consistent Map-Reduce
API for vshard.

Core of the patchset - 3 last patches: new module 'storage.ref', new module
'storage.sched', and router's new function `map_callrw()`.

The other patches are preparatory. They mostly introduce and unit-test helpers
used in the last patches.

For details see the commit messages.
