Couldn't create a new ceremony when environment variables are not attached to deployed Cloud Functions

[baumstern]

There is a template for environment variables in /backend package. But the user can deploy Cloud Functions without configuring those values. In this case, phase2cli coordinate setup command fails like following, because it couldn't create S3 bucket internally due to missing API key:

✔ Circuit metadata read and saved correctly

Actually, the error log had printed due to S3 soft limit:

createBucketwf32r05w6pab Error: [ERROR] Generic error when creating a new S3 bucket: TooManyBuckets: You have attempted to create more buckets than allowed at entryFromArgs (/workspace/node_modules/firebase-functions/lib/logger/index.js:130:19) at Object.error (/workspace/node_modules/firebase-functions/lib/logger/index.js:116:11) at logMsg (/workspace/dist/src/functions/index.node.js:125:41) at /workspace/dist/src/functions/index.node.js:1875:9 at processTicksAndRejections (node:internal/process/task_queues:96:5) at async /workspace/node_modules/firebase-functions/lib/common/providers/https.js:438:26

Will investigate environment variable case separately
