Alternative to 'glide up' when modifying 'glide.yaml'
In https://github.com/deis/workflow-cli/pull/128 we added logic around modifying a local glide.yaml with particular pkg/version values sent from the upstream controller-sdk-go PR job before building.
However, as noted in https://github.com/deis/workflow-cli/pull/128#discussion_r71023996, this may update other dependencies when we strictly only want the sdk dependency updated. Therefore, this ticket represents researching a better way to bring in a particular PR change in controller-sdk-go...
It appears the ability to glide up <particular/pkg> is being tracked upstream/in glide by https://github.com/Masterminds/glide/issues/252
