* Add transports based on Azure PaaS
This pull request adds two new transport implementations:
- `azurestoragequeues` is implemented on top of Azure Storage
Queues [1]. This offers a simple but scalable and low-cost PaaS
transport for Celery users in Azure. The transport is intended to be
used in conjunction with the Azure Block Blob Storage backend [2].
- `azureservicebus` is implemented on top of Azure Service Bus [3] and
offers PaaS support for more demanding Celery workloads in Azure. The
transport is intended to be used in conjunction with the Azure
CosmosDB backend [4].

* Exclude Azure transports from code coverage
There is test coverage for the transports but the tests require Azure
credentials to run (passed via environment variables) so codecov doesn't
exercise them.
