Add noauth support

[j-griffith]

This adds the basic config checking for noauth and creates a service client appropriately. This also requires an update to the glide version of gophercloud to a newer version that includes the newly added noauth package.

Looks good to me!

@j-griffith I just tested this with my setup and it works well. Could we push to get it merged?

/area openstack/standalone-cinder

pls run go get github.com/sgotti/glide-vc && glide-vc --use-lock-file, it's just to minimize the amount of vendor code we check in. I will merge!

[j-griffith]

@wongma7 Ahh, thanks! I was wondering about the glide updates!!

[wongma7]

/lgtm

[wongma7]

oops, glide-vc deleted the package we need :/

please edit the glide.lock file so it has the package: then do glide install -v; glide-vc --use-lock-file to get the noauth package again and prevent it from getting inadvertently deleted

   subpackages:
   - openstack
   - openstack/blockstorage/extensions/volumeactions
+  - openstack/blockstorage/noauth
   - openstack/blockstorage/v2/snapshots
   - openstack/blockstorage/v2/volumes
   - openstack/common/extensions

(sorry for lack of docs around how we use glide, I am hoping we can move to golang/dep soon since that is supposed to be a much better experience)

[j-griffith]

Thanks @wongma7 I noticed the failure and was digging at Glide to try and fix that. I actually was thinking of proposing an update to godep, but looks like that might take some coordination. Anyway, thanks again!!

Was glide install -v; glide-vc --use-lock-file run before this was merged?

Running glide install -v; glide-vc --use-lock-file on master, removes around ~ 60k lines of code in vendor/github.com/gophercloud/gophercloud/openstack, code which was added in this commit.

I'm only asking, because I'm vendoring github.com/digitalocean/godo in #470, and it seems a bit odd, that adding a new dependency removes ~ 75k lines.

[wongma7]

@klausenbusk appears not, oops. you are not doing anything wrong, your looks okay to me: perhaps I could do a separate PR just to run glide install -v; glide-vc --use-lock-file again but anyhow the repo will reach desired state eventually

[j-griffith]

@klausenbusk Sorry about that, @wongma7 actually pointed that out and I thought I had it sorted but it would appear I missed something upon the actual commit. I've submitted #471 to clean that up.

[klausenbusk]

@klausenbusk Sorry about that

No problem :)

I've submitted #471 to clean that up.

Thank, I will rebase when it has been merged.
