Maximum number of keys on account reached

[anouarchattouna]

Every time gcp broker is installed sc add-gcp-broker, a new json key is generated locally. After few retries, the maximum number of keys on account is reached :

Failed to configure the Service Broker
Error: error creating service account key: failed to create service account key: ERROR: (gcloud.iam.service-accounts.keys.create) RESOURCE_EXHAUSTED: Maximum number of keys on account reached.
- '@type': type.googleapis.com/google.rpc.RetryInfo
  retryDelay: 86401s
 : exit status 1

Is there a way to check the installation before executing sc install and sc add-gcp-broker or use (somehow) an existing key ?
