Fixes connecting issues with OpenShift

[cdrage]

Due to https://github.com/openshift/origin/commit/b7b6c01bc7d7c7592cce263da07a727e3758bd4b which prevents the usage of the token via URL within OpenShift, the token MUST be passed via the headers 'Authorization' parameter on HTTP requests.

This commit adds the bearer token in order to fix an issue connecting to OpenShift Origin 1.3

code mostly LGTM.. a few questions though:

1 - Can you test with the oc new-app functionality (link) - I assume it still works fine, but just want to make sure 1 - Can you test to make sure it still works with old versions of openshift - i.e. the one in the CDK?

1. oc new-app works (albit it takes a while for it to install.. is this normal?
2. 1.1.0 works

oc new-app (just used 'lol' as the docker image name since wanted to try a random name for no conflicts)
