Project Staffing Deployment fails when DataBricks runtime environment is temporary unavailable

[Denis Serdyuk]

Describe the bug
Deployment script fails sometimes with following error:

Provisioning ADB cluster ...
Creating a new cluster default-gdc-cluster
Databricks cluster initialization has failed
400 Client Error: Bad Request for url: https://adb-2879709616442315.15.azuredatabricks.net/api/2.0/clusters/create
 Response from server: 
 { 'error_code': 'BAD_REQUEST',
  'message': 'Current organization 2879709616442315 does not have any '
             'associated worker environments'}
Traceback (most recent call last):
  File "/home/vsts/.gdc-env/lib/python3.8/site-packages/databricks_cli/sdk/api_client.py", line 121, in perform_query

requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: https://adb-2879709616442315.15.azuredatabricks.net/api/2.0/clusters/create

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "post-deployment.py", line 97, in <module>
    raise adb_err
  File "post-deployment.py", line 87, in <module>

However subsequent rerun of the script works for the same organization. Probably it's related to eventual consistent nature of of ADB metadata database..

Expected behavior
ADB Cluster provisioning should be more resilient to temporal issues like that and retry cluster creation.
