[Tarantool-patches] [PATCH] Add wait_vclock_ignore0 compare function

[Sergey Kaplun <skaplun@tarantool.org>]

Function wait_vclock is unsuitable for waiting vclock, when there are
inserts in local spaces. Function wait_vclock_ignore0 waits for
corresponding vclock ignoring zero component.

Needed for #3363
