[Feature Request] Equivalent PowerShell commands

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

Azure DevOps CLI is the only commandline tool available to our customers. However, it can be messy for users who prefer PowerShell as their scripting language, because they have to mix PowerShell syntax with CLI syntax.

**Describe the solution you'd like**

Azure PowerShell provides a tool named [autorest.powershell](https://github.com/Azure/autorest.powershell) that can generate powershell modules from [swagger spec](https://github.com/MicrosoftDocs/vsts-rest-api-specs). The proposed solution is to leverage autorest to generate some core commands into a PowerShell module.
