Add support for Tencent Cloud and Alibaba Cloud for BYOC

[XVilka]

Since you probably use Hashicorp's Terraform, and you already support Azure, AWS, GCE, etc, it might be also useful to support also the other cloud providers too.

• https://www.terraform.io/docs/providers/tencentcloud/index.html
• https://www.terraform.io/docs/providers/alicloud/index.html

And any other popular clouds from https://www.terraform.io/docs/providers/type/major-index.html and https://www.terraform.io/docs/providers/type/cloud-index.html

We use HashiCorp Packer to build images. All scripts and Packer templates used by BYOC framework are open-source.

Unfortunately, the framework not documented for now. In short, PowerShell module use connect-AppveyorToXxx.ps1 scripts (and AppVeyorBYOC-Common.ps1 contains reusable bits of PowerShell code), those scripts gather all necessary info, prepare Cloud of your choice and start packer with one one of the templates:

• minimal-ubuntu.json,
• minimal-windows-server.json

You may fork this repository, add Alicloud and Tencentcloud builders to packer templates of your interest.

From our side, we have to add Alicloud support to the Appveyor Server and Appveyor Build Agent. You might help us to get up to speed with Alicloud. I suppose Ali cloud is very similar to AWS:

• one should provide access and security keys to access cloud resources,
• have similar to AWS instance types (What Alicloud instance type similar to m4.large in your opinion?)
• have same metadata service to pass data to VM Am I correct on those assumptions?

I heard you use .NET for development, so this probably can help you:
