[tools/perf] Skip try job run if trybot config file does not change

Sometime, users run trybot job against many bots of different platforms
(e.g:  platforms win & winx64). Sometimes the configs of these different
platforms are the same because they happens to share the same bot.

In this case, we will skip the trybot run if the config file does not change.

I am unsure with logging to use, error, warning & debug don't seem right. I
think it's ok to surface this kind of info to the users, hence we use print
here.
