[tarantool-patches] [PATCH v1] test: replication/misc fix for high load

[Alexander V. Tikhonov]

Fixed test replication/misc to be able to run it on
hosts under high load. Changed downstream check to
use test_run:wait_downstream() function, to wait for
certain box.info.replication values to fix the error:
