Remove dependency on github.com/deis/pkg/time

[arschles]

I believe github.com/deis/pkg/time is only used in one place - for time formatting between the server and the client. However, this package comes with dependencies on k8s.io/kubernetes/pkg/..., which is huge. This issue is for removing the dependency altogether, so that we don't have to pull in a 100MB+ (iirc) dependency to get 1 constant

I'll take a look into this after I finish migrating the CLI to use the SDK!

It seems like the best short term fix is to copy it into the sdk, so I did that in #8
