/// This is a simple named failpoint library inspired by https://github.com/pingcap/tiflash
/// The usage is simple:
/// 1. define failpoint with a 'failpoint_name' in FailPoint.cpp
/// 2. inject failpoint in normal code
/// 2.1 use fiu_do_on which can inject any code blocks, when it is a regular-triggered / once-triggered failpoint
/// 2.2 use pauseFailPoint when it is a pausable failpoint
/// 3. in test file, we can use system failpoint enable/disable 'failpoint_name'
