[Tarantool-patches] [PATCH 0/2] fix vlock obtainment on join & join_vclock test

[Ilya Kosarev]

First patch fixes vclock obtainment on join for master, as far as in
case of high load vclock used to join replica could be in advance
comparing to an actual WAL and therefore replica could have missed some
tuples from master.
Second patch fixes flaky join_vclock test and splits off explicit test
for changes apply order on replica.
