Specify Example Caching Directory

Is your feature request related to a problem? Please describe.
Would be great to specify the directory gradio uses to cache examples. This would allow developers to save the cache to persistent storage on HF Spaces.

Describe the solution you'd like
Support specifying the cached directory via environment variable and a parameter in the examples class.

For files created during the application's lifetime, users can determine the directory where those files are created via GRADIO_TEMP_DIR variable. That can't be done for examples. They always get cached to gradio_cached_examples in the directory where the python launch command was called from.

Hello @freddyaboulton, I would love to work on this issue actively, but I am not able to understand what is required to be done.
And like from which folder am I supposed to work on, I'm not able to understand.
Kindly guide me through.
Thanks :)
