please update github.com/Azure/azure-sdk-for-go vendoring

[nim-nim]

The vendored github.com/Azure/azure-sdk-for-go version is obsolete and relies on code of dubious legal status (the godo bits). Please update to a current release which has not got this problem anymore.

I will prepare a PR for this

Any news on that?

I'm attempting to package docker-distribution for Debian, and hence to build it against the Go libraries shipped by Debian (no vendoring). And right now in Debian unstable, we have azure-sdk v10.

When I try to build against v10 I get these errors.
