Feature request: Read gin file from google cloud bucket path

[OhadRubin]

Hey,
I've seen libraries like T5X that are able to read model configs from cloud buckets.
As a product from google I kind of expected this feature to be implemented here and was surprised to find it wasn't.
Implementation plan:

1. save gin file from remote path into a temporary file
2. use that as the gin file

Hi @OhadRubin, after some time searching for a solution, I found this code:

gin-config/gin/tf/utils.py

Line 31 in 1b6f054

config.register_file_reader(tf.io.gfile.GFile, tf.io.gfile.exists)

Using it I was able to read gin files from a GCS bucket. I think that frameworks like T5 and T5x are able to to it because they also import this code.

Best,
Marcos

I actually found this at some point too, this should really be added to the documentation!

Yes, it really should!
