*: rename import paths to "go.etcd.io/etcd"

[gyuho]

Fix #9965.

This only updates the necessary ones to wrap up our github org migration. Some still reference to github.com/coreos/etcd (e.g. v2 docs, old branches). Will change rest in the following PR.

Note: this does not add canonical import paths (https://golang.org/doc/go1.4#canonicalimports), which I don't think is necessary--Kubernetes does not use it either.

/cc @philips @xiang90 @jpbetz

[gyuho]

Proto gen has some issues with swagger doc... Will debug separate. Reverted the change for now.

[philips]

LGTM

[vimalk78]

whats the effect on developers?
just do a fresh git clone or go get from github.com/etcd-io/etcd and add remotes newly?
or there is a go specific way to move the project from one path to another

[gyuho]

You can just move git to ${GOPATH}/src/go.etcd.io/etcd, and sync with upstream master branch.

@jpbetz Aside: the preferred pkg prefix going forward should be go.etcd.io/etcd

[jpbetz]

Thanks @philips I'll update the above comment to match.

[jingyih]

Thanks @jpbetz for the detailed explanation and suggested fix. I think we should make this more visible to the etcd community.

@jpbetz Thanks for the detailed explanation. This is exactly the issue I was having. I don't have a dependency on etcd master, so I can use a release version. Since we will eventually have to handle newer etcd releases, for now, I will move to go.etcd.io/etcd and give it a try.

Thanks
Khen

i'm import this package "go.etcd.io/etcd/clientv3" is this panic error ?
I tried to do it. rm -f ....../src/go.etcd.io/etcd/vendor/golang.org/x/net/trace/trace.go but invalid！

panic: /debug/requests is already registered. You may have two independent copies of golang.org/x/net/trace in your binary, trying to maintain separate state. This may involve a vendored copy of golang.org/x/net/trace.
