Test-pmd already has a way to run a list of commands from file, but there
is no way to pause execution for a specified amount of time between two
commands. This may be necessary for simple automation, particularly for
waiting on some asynchronous operation such as link status update.
Add a simple sleep command to wait until certain number of milliseconds has
passed.
