   ### SUMMARY
   <!--- Describe the change below, including rationale and design decisions -->
   Fix for issue - https://github.com/apache/superset/issues/23295
   
   After enabling the domain sharding as follows
   
       ENABLE_CORS = True
       CORS_OPTIONS = {
         'supports_credentials': True,
         'allow_headers': '*',
         'resources': '*',
         'origins': 
['https://dashboards.mydomain.com','https://dashboards1.mydomain.com','https://dashboards2.mydomain.com','https://dashboards3.mydomain.com']
       }
       
SUPERSET_WEBSERVER_DOMAINS=['dashboards.mydomain.com','dashboards1.mydomain.com','dashboards2.mydomain.com','dashboards3.mydomain.com']
   All 4 webserver domains are set via DNS A record to the same IP address.
   
   When navigating to a dashboard, I can see in the Edge devtools, that the 
/api/v1/chart/data requests are sent to all webserver domains. However, they 
all fail with "401" (unauthenticated). I can also see, that some of the 
requests have a response set to {"msg":"Missing Authorization Header"}.
   
   ### EXPECTED RESULT
   Domain sharding uses the 4 configured webserver domains for requesting data 
- and uses the session cookie of original domain for authentication.
   
   ### ACTUAL RESULT
   The authentication of the non-original webserver domains does not work and 
the requests are not authenticated.
   
   ### TESTING INSTRUCTIONS
   <!--- Required! What steps can be taken to manually verify the changes? -->
   Please verify changes from my fork. 
   After setting the `SESSION_COOKIE_DOMAIN` to main domain in 
`superset_config.py` authrization should work on all the domain shards.
