[Bug 1564812] Re: Disable sudo io logging for rootwrap

[James Page]

I think its good to have the input log for auditing purposes; however
output is probably surplus in this instance.

Title:
  Disable sudo io logging for rootwrap

Bug description:
  Cinder, Neutron and Nova use rootwrappers that allow selected commands
  to be executed with root privileges via sudo. If an adminstrator
  chooses to enable sudo logging for security reasons, this will cause a
  lot of files being created, leading to filled up file systems pretty
  fast. This could be circumvented by changing the entry in
  /etc/sudoers.d/cinder_sudoers like this:

  --- /etc/sudoers.d/cinder_sudoers       2016-03-30 11:20:28.000000000 +0000
  +++ /etc/sudoers.d/cinder_sudoers.new   2016-04-01 09:31:36.811807794 +0000

  and similarly for nova and neutron.
