Get autotune configs

[Luke20000429]

The autotune feature is great but takes time in the first several rounds.
How to get the dictionary of autotune results after running a few cycles? In that way, I can hardcode the config choice in the release version.

you can set env var: TRITON_PRINT_AUTOTUNING=1 or you can also do print(kernl.best_config) after running auto tuning

If I've known the best configs after autotune, is there any way to save the dict of configurations so that I can load that directly in the next time? Using triton.heuristics¶ can specify the meta data, but how to specify num_stages num_warps etc.?
