Github issue裡MVP和Stretch label的差別

Github issue裡，大家往往可以看到有issue被加上了這兩種label，且這兩種label是互斥的。這裡介紹其差別：

anything marked MVP is what we want to get done in first iteration of the feature, however, that doesn’t exactly have to match with code that is finished and released (merged to develop and it gets into a new minor)

anything marked stretch should be done last, meaning stretch tickets live in stretch column
