gobizflycloud go.mod breaks go mod vendor

[avorima]

The bizflycloud provider (#4009) introduced an SDK with a go.mod that's not vendored which causes failures.

$ cd cluster-autoscaler
$ go mod vendor
go: finding module for package k8s.io/autoscaler/cluster-autoscaler/cloudprovider/bizflycloud/gobizfly
go: found k8s.io/autoscaler/cluster-autoscaler/cloudprovider/bizflycloud/gobizfly in k8s.io/autoscaler/cluster-autoscaler/cloudprovider/bizflycloud/gobizfly v0.0.0-20210511160736-2e6ccacee698
go: k8s.io/autoscaler/cluster-autoscaler/cloudprovider/bizflycloud imports
        k8s.io/autoscaler/cluster-autoscaler/cloudprovider/bizflycloud/gobizfly: k8s.io/autoscaler/cluster-autoscaler/cloudprovider/bizflycloud/[email protected]: parsing go.mod:
        module declares its path as: github.com/bizflycloud/gobizfly
                but was required as: k8s.io/autoscaler/cluster-autoscaler/cloudprovider/bizflycloud/gobizfly

My current local solution is to remove the go.mod that's causing problems.

I couldn't find the OWNERS of said cloudprovider, but pinging @lmq1999 since they contributed the code.

Thanks for catching this, I was just going to create the same issue. It's also preventing us from updating vendor in the repository. I'm going to delete the go.mod file for now. @lmq1999 - I think ultimately leaving just the go source files makes the most sense, but I'll leave it up to you.

@towca Thanks!
