[Tarantool-patches] [PATCH v2 vshard 0/2] storage: allow replica to boot before master

[Vladislav Shpilevoy]

The patchset fixes a problem appearing in tarantool cartridge when
replica is configured before master and fails with an ugly error
without a serious reason for that.

As a prerequisite the reload evolution subsystem is fixed, because
it had a bug affecting the main commit. The bug didn't appear
earlier, because the evolution was never used for anything so far.

Changes in v2:
- The reload evolution fix is moved into a separate commit;
- Instance un-installs _bucket trigger when master is switched to replica.
