set close_fds=True in Popen

The current way of using Popen does not close pipes properly,
and therefore long-running keystone processes, which depends on
keystoneclient.common.cms for data sigining, eventually hit
open file limit and stop working. Passing close_fds=True seems
to have solved the problem.
