Fix valgrind issues with configurable_test (#7424)

Summary:
Valgrind was reporting a problem with the configurable_test in some GTEST code.  This problem was caused by using a std::function as a GTEST parameter.  This change changes the test to use a string as a function parameter (backed by a map) and fixes the valgrind issue.
