Irregular use of go tag

[bejens]

Describe the bug

Upgrades that are not compatible in the go language should use the following forms: https://blog.golang.org/v2-go-modules instead of simply upgrading tags, this is because go get -u will upgrade the direct and indirect dependencies in the project. This will upgrade the indirect dependencies if possible Will cause code incompatibility, as shown below:

To Reproduce Steps to reproduce the behavior:

I have 2 projects A, B, and B depends on A, A depends on go2sky@v0.3.0:

A: v1 (dep: go2sky) B: v1 (dep: B)

when you use go get -u in B project. A(direct dependency) and go2sky (indirect dependencies) will upgrade to latest, If the v0.5.0 version of go2sky is not backward compatible, B project will get error

Expected behavior

Incompatible upgrades can follow golang version management specifications

v2-go-modules seems like a good idea. Can we talk about it over WeChat? my email zhangwei24@apache.org :)
