[tarantool-patches] [PATCH 4/5] swim: speed-up tests

[Vladislav Shpilevoy <v.shpilevoy@tarantool.org>]

With following patches some of the tests will work much slower
due to significantly increased size of the most of packets.

This commit tries to smooth it by

    * Turning off verbose logs in unit tests;
    * Using much more light version of UUID comparator.

According to the profiler these places increase speed in a
couple of times, and at the same time they are simple.

Needed for #4253
