Support Azure DevOps in Pipeline Commands

[jongio]

Today azd pipeline config supports GitHub workflows. Let's also add support for Azure DevOps Pipelines

A sample pipeline and full instructions in README to get it all setup can be found here
https://github.com/Azure/azure-dev/tree/main/templates/common/.azdo/pipelines

1. Every template should include both
2. azd pipeline config will default to GitHub
3. Add a param, something like --provider {github|azdo} to facilitate more providers in the future

Plan

1. Define azd connection model to Azure Dev Ops #236
2. Define and implement connection between Azure DevOps and Azure #237
3. Define and implement the user story around azd pipeline with Azure DevOps #238
4. Update all templates with Azure DevOps pipeline for provision, build and deploy #239
