This patch adds a Python script that can be used to analyze the
revalidator runs by providing statistics (including some real time
graphs).
The USDT events can also be captured to a file and used for
later offline analysis.
The following blog explains the Open vSwitch revalidator
implementation and how this tool can help you understand what is
happening in your system.
