yaml_config::YamlConfig should reuse the tests of formats

[apolukhin]

yaml_config::YamlConfig has the same interface as formats::*::Value. Reuse the Value tests from https://github.com/userver-framework/userver/tree/develop/universal/src/formats/common/value_test.hpp for yaml_config::YamlConfig the same way as it is done for YAML

https://github.com/userver-framework/userver/blob/4348f91c9251bdfbb596ae68c5c922205b04c8fc/universal/src/formats/yaml/value_test.cpp#L17

Internal ticket: 8685

Looks like it has been already done long time ago: https://github.com/userver-framework/userver/blob/738190a4f0070f683d29399fb47db2246e89d53c/universal/src/yaml_config/yaml_config_test.cpp#L28 by that commit Also, I checked that tests actually instantiate and run for this type, here is output:

$ ./build_debug/universal/userver-universal-unittest --gtest_filter=*YamlConfig*
Running main() from gmock_main.cc
Note: Google Test filter = *YamlConfig*
