Switch to glide from godeps

[dlorenc]

See #33.

Glide gives more control in pinning the versions of dependencies, like k8s.io/kubernetes. It might make it easier to update to newer versions of k8s than godep currently does.

Thoughts?

Glide still has a couple of issues that might be of concern -

Masterminds/glide#367
Masterminds/glide#368
Masterminds/glide#319

I'd recommend holding on to godep, until the issues mentioned above are fixed in glide. Switching to the vendor directory is itself a good first step.

I guess it's a case of the lesser of two evils... I just spent a few hours trying to update the kubernetes components we use, and I got stuck on kubernetes/kubernetes#23529

:(

@dlorenc Which godep version are you using?

Switching to the vendor directory is itself a good first step.

@vishh Don't know if you noticed, but we've used vendor/ from the beginning :)

I've tried HEAD, 53 and 63 I think. They've all failed in different, mysterious ways. One of them left .git repos all over my vendor directory which basically broke everything.

I almost have stuff building with glide and k8s at head though. I'm chasing down a few int<->int32 swaps that I think @luxas was responsible for :)

I'll try to push it tomorrow to show what it looks like.

Closing this for now, we can revisit if/when k8s makes the switch.
