    Disabling Google Cloud support

Config file saved to /Users/hanqingliu/.skyplane/config
To disable performance logging info:
https://skyplane.org/en/latest/performance_stats_collection.html

Environment info (please complete the following information):

• OS: Mac OS
• Python 3.10.10
• Skyplane 0.2.1

Additional context
We have an institution cloud admin who helps creating projects. My account probably doesn't have permission to set IAMs for skyplane service account.

Thanks!

Hi @lhqing - thanks for posting this! Do you have any other service accounts with permissions to access cloud object stores that you can get a key file for? Unfortunately we need service account credentials to access the Google Cloud Storage APIs.
