[Bug 903993] [NEW] Don't hang waiting for input from commands

[Drew Mazurek]

Public bug reported:

If a command is interactive and opens up stdin, the entire deploy will
hang.  cloud-init should close stdin if anything tries to open it.
Examples of this are:

- apt-add-repository ppa:xxx/yyy

or

- apt-get install foo

(Specifically without the -y option.  -y on those commands would be a
workaround for this bug.)

** Affects: cloud-init (Ubuntu)
     Importance: Undecided
         Status: New
