Add "env" parameter in Kubernetes context

This new parameter, "env", will allow the user to
automatically to add environment variables in a pod definition

Example of definition in a context:
  context:
    type: Kubernetes
      servers:
        host:
            image: ...
            commands: ...
            env:
                - <variable name>: <variable value>
                - <variable name>: <variable value>

The volume type and the definition must be one of the supported
ones in Kubernetes [1].
