    [BEAM-1648] Replace gsutil with storage API calls

    This PR replaces the `gsutil cp` call with a GCS API call when staging 
resources.
    
    I was unsure how to unit test this feature, and given that the existing 
functionality was not under test already, I just tested this with the following 
script:
    
    ```python
    from apache_beam.runners.dataflow.internal import dependency
    dependency._dependency_file_copy('/home/david/myfile.txt', 
'gs://mybucket/myfile.txt')
    dependency._dependency_file_copy('gs://mybucket/myfile.txt', 
'gs://mybucket/myfile2.txt')
    dependency._dependency_file_copy('gs://mybucket/myfile2.txt', 
'/home/david/myfile2.txt')
    ```
    All three operations are successful.
    
    I've set up travis-ci for the build, and it is successful for the python 
tests but not the Java tests (it looks like this is a general issue at the 
moment).
