Benjamin Schanzel b76a0f458e OpenShift/k8s Provider: Allow passing env vars to Pods
For the OpenShift and Kubernetes drivers, allow passing env vars to the
Pod nodes via their label config.
It is not possible to set persistent env vars in containers on run time
because there is no login shell available. Thus, we need to pass in any
env vars during node launch. This allows to set, e.g., ``http_proxy``
variables.

The env vars are passed as a list of dicts with ``name`` and ``value``
fields as per the k8s Pod YAML schema. [1]

```
- name: pod-fedora
  type: pod
  image: docker.io/fedora:28
  env:
  - name: foo
    value: bar
```

Support for passing environment variables to k8s and OpenShift Pod build
nodes has been added.
It is not possible to set persistent env vars in containers on run time
because there is no login shell available. Thus, we need to pass in any
env vars during node launch. This allows to set, e.g., `http_proxy`
variables. Environment variables can be defined on node labels as a list
of dictionaries with `name` and `value` fields as per the k8s container
YAML schema.
