Forward Jenkins env vars to worker machine
Forward Jenkins env vars to worker machine

For https://codecov.io/ to be able to detect a CI provider (Jenkins in this case) some environment variables need to be present. See [this script](https://github.com/codecov/codecov-bash/blob/e87e79f5c78e99f0a46ca55e07690776f641c7c8/codecov#L365) for more information about this. Codecov.io advocates the usage of this script: https://codecov.io/bash

The plan with this commit is to pass the environment variables from the jenkins slave to the worker machine.
