[Bug 810157] [NEW] support '-' for writing to stdout in nova-manage environment/zip

[Scott Moser]

Public bug reported:

traditionally, unix commands support a '-' to indicate that content should be written to stdout rather than a file.
It would be nice if 'nova-manage environment' would do this.

ie:
$ sudo nova-manage project environment test-project admin - | grep NOVA_URL
  import pkg_resources
export NOVA_URL="http://10.202.9.127:8774/v1.0/"
