Outdated cloud_tpu.py script

[tlatkowski]

Description

I've tried to reproduce the training procedure for the speech transformer model (https://github.com/tensorflow/tensor2tensor/blob/master/docs/tutorials/asr_with_transformer.md) but encountered some difficulties.

It looks like cloud_tpu.py script is outdated in comparison to the current gcloud api, like: exectuting "gcloud beta compute tpus list" command.

I had to make some workarounds and fixes locally to make it work, what do you think about updating cloud_tpu script to be in line with current gcloud API? ...

I'm closing this issue as cloud_tpu scripts was removed. Current version of TPU support follows the official TPU tutorial.
