  -----------
  [clang-tidy] Optional inheritance of file configs from parent directories 

Summary:
Without this patch clang-tidy stops finding file configs on the nearest
.clang-tidy file. In some cases it is not very convenient because it
results in common parts duplication into every child .clang-tidy file.
This diff adds optional config inheritance from the parent directories
config files.

Test Plan:

Added test cases in existing config test.
