Replace subprocess "check_output" with "Popen"
"check_output" is a blocking wrapper for "Popen" which returns the output of the command execution or raises an exception in case of error. "Popen" is a non-blocking function that allows to create asynchronous tasks. It returns any possible execution error but doesn't raise an exception; this is delegated to the developer. This code is used in the Yardstick CLI base test class. Change-Id: Ie3e1228b2d40cb306354447653678bf581bc9697 Signed-off-by: Rodolfo Alonso Hernandez <rodolfo.alonso.hernandez@intel.com>
