Hi, Igor!
Thanks for the patch!
Please consider my comments below.
 
> 
>>This patch provides two enhancements for <utils.skipcond>:
>>1. As a result of the patch, <utils.skipcond> becomes multi-conditional,
>>   so there is no need to concatenate one huge and complex condition
>>   with one huge unreadable reason. Now skipcond receives the table with
>>   conditions and skips the test if one of the given conditions is met.
>>2. <utils.skipcond> yields the test object, that allows to chain
>>   skipcond call right next to the test constructor.
>>
>>Finally as a result of the aforementioned changes <utils.skipcond> is
>>moved to tap.lua.
>>
>>Relates to tarantool/tarantool#8252
