Azure Blob Storage URL creation requires different construction of connection

[devine12]

Is your feature request related to a problem? Please describe.
Currently in the api_policy_source the url that is constructed append bundle.tar.gz to the end of the url. For Azure Blob Storage a SAS token is required at the end of the url.

Current state:
{url}?{SAS_TOKEN}/bundle.tar.gz

Required State:
{url}/bundle.tar.gz?{SAS_TOKEN}

Describe the solution you'd like
The solution our team has added will construct the correct url with some additional identity management when given the correct env-vars as shown in the documentation.

Describe alternatives you've considered
Alternatives were to create a proxy between OPAL and the blob storage but we would rather have this functionality baked in.
