AzureStorage fails with valid connection string using shared access signature

[KristofBruyninckxOmina]

In version 4.2, additional checks have been added to the initialiser of AzureStorage

django-storages/storages/backends/azure_storage.py

Lines 132 to 134 in d1cd2db

	if self.connection_string and (not self.account_name or not self.account_key):
	self.account_name = re.search(r'AccountName=(\w+);', self.connection_string)[1]
	self.account_key = re.search(r'AccountKey=(.*);', self.connection_string)[1]

However, when using a connection string with shared access signature, the account name, and specifically, the account key should be omitted.

From azure docs https://learn.microsoft.com/en-gb/rest/api/storageservices/delegate-access-with-shared-access-signature:

A shared access signature (SAS) is a URI that grants restricted access rights to Azure Storage resources. You can provide a shared access signature to clients who should not be trusted with your storage account key but whom you wish to delegate access to certain storage account resources. By distributing a shared access signature URI to these clients, you grant them access to a resource for a specified period of time.

Because of the additional checks, a connection string that worked fine on v1.13.2 now fails on v1.14

Thanks for the report, the fix is now going in.
