Crank SignalR Testing topology in Azure

We want to create a testing environment for perf testing SignalR in Azure using Crank. Some details of this topology:

* [ ] VM running the Crank server
* [ ] 5 ACI's, each running a containerized app that connects to the Crank-hosted Hub and starts sending messages

Thing to be done (team, please augment, let's **write it down**):

* [ ] @bradygaster to write a bicep template to create the VM and other Azure resources
* [ ] @bradygaster to send a PR for the bicep file once it's creating resources properly
* [ ] tbd to provide a sample server and client project to do the work
* [ ] tbd (probably @bradygaster) to write script that installs/configures/runs the Crank server on the VM
* [ ] tbd (probably @bradygaster) to write script that builds the docker images and publishes them to ACR and fires up the ACI instances so they can turn the crank
* [ ] tbd to provide other items @bradygaster forgot or omitted here
