release. In getting ready for ansible 2 (and our ability to delete our
local copy of the file, I noticed we had a couple of minor cleanups.

Also, the timeout command is there to improve life and workaround puppet
deficiencies. However, it's not working around deficiencies on systems
that do not have the timeout command if we blindly use it.

The puppet specific timeout options are more complex and out of scope of
this.

Issue: #1273
