[GoTool] Make the Go download URL configurable

[dagood]

Required Information

Type: Feature
Task Name: GoTool

Environment

• Azure Pipelines, any version used in Microsoft internal builds
• Agent - any

Issue Description

My team is building Go for internal use at Microsoft, but we don't have a good way for people who use the GoTool@0 task to switch over from the official build of Go to our build of Go. I think all we need is a way to configure the base URL rather than hard coding it:

azure-pipelines-tasks/Tasks/GoToolV0/gotool.ts

Lines 96 to 98 in 7893ce0

	function getDownloadUrl(filename: string): string {
	return util.format("https://storage.googleapis.com/golang/%s", filename);
	}

URLs for our builds will be something like https://aka.ms/golang/release/%s.

We don't want to change the default base URL: Azure Pipelines users outside Microsoft should continue to get the official Go binaries. (Our build of Go is only intended for use within Microsoft to meet supply chain and FIPS requirements. For more info, the Microsoft build of Go is maintained at https://github.com/microsoft/go.)

I think it will also need a modification to the cache logic to use the source URL in the key
