Demonstrate deployment of Burr UI on Azure

**Is your feature request related to a problem? Please describe.**

We have the [s3 server](https://github.com/DAGWorks-Inc/burr/blob/main/burr/tracking/server/s3/README.md) as well as a fairly complex set of terraform files, but we don't have a simple deploy on Azure tutorial.

**Describe the solution you'd like**

A documentation page/example for how to deploy on GCP. We will link from the docs.
Terraform would be nice too!

Ideally:

- Inside a VPN
- Uses S3 equivalent with blob storage: https://bluexp.netapp.com/blog/aws-vs-azure-cloud-storage-comparison#:~:text=AWS%20object%20storage%20comes%20in,storage%20services%20for%20unstructured%20data.
- Simple, single-tenant server (no need for horizontal scaling as we are not write-bound)

Note this is more complex -- we'll need to figure out how to get azure + S3 to work together. Will likely want to recommend something like https://flexify.io/s3-azure or rewrite the client to work with azure blob storage, + reuse server. Could also explore a distributed filesystem, although it won't be as scalable.
