Connecting to Azure Servicebus - Handling special characters in key

[pajoma]

I created a new azure servicebus resource and tried the following connection URL (in Airflow, values as examples)

azureservicebus://MySharedAccessKey:2+x9jI6mubSX3s/XhAfA34WWSh2Vif+bxbJWZsaG=@my-namespace

which resulted in the error invalid literal for int() with base 10: 'x9jI6mubSX3s'. The airflow documentation proposed to replace the character / with %2F

azureservicebus://MySharedAccessKey:2+x9jI6mubsx3Sss3s%2FXhAfA34WWSh2Vif+bxbJWZsaG=@my-namespace

which helped for the parsing, but resulted in a 401 Unauthorized (InvalidSignature: The token has an invalid signature)

I managed to connect to the queue by regenerating the key until I got one with a special character.

The issue is mentioned in the source, but I don't see a solution there. Maybe print a log message with the hint to quote the / in the connection string (which still doesn't address the issue, why a quoted string raises the unauthorized error)
