mock: in order mock calls

[ReyOrtiz]

Summary

Add helper method to declare the order of the mock calls.

Changes

• add InOrder(calls ...*Call) helper method to declare the order of mock calls by calling NotBefore()

Motivation

This is probably the only feature I miss from gomock.InOrder(), it is more intuitive and cleaner to declare the order of the mock calls. Probably most cases can be satisfied with this method.

InOrder(
    mockedService1.On("TheExampleMethod", 1, 2, 3).Return(4, nil),
    mockedService2.On("TheExampleMethod2", true).Return(),
    mockedService3.On("TheExampleMethod3", "abc", 3).Return(false, nil),
)

Hello, any ETA on merging this PR?

[brackendawson]

Thanks @ReyOrtiz. This can be consumed now by gomock expats with: go get github.com/stretchr/testify@master. Once testify v1.10 is released it can be consumed as per the README. I'll have a look at drafting a release soon.

Thanks @brackendawson for all the help! 🙏
