VSTS organization URL helper samples

[willsmythe]

Samples showing how to properly construct a URL to a VSTS organization (formerly called "account") using either its name (e.g. "Fabrikam") or its GUID identifier.

Example of how to use the new helper:

public async Task DoSomething() { Uri orgUrl = OrganizationUrlHelpers .GetConnectionUrl("myOrgName"); // typically resolves to https://myorgname.visualstudio.com VssConnection orgConnection = new VssConnection(orgUrl, credentials); BuildHttpClient buildClient = orgConnection.GetClient<BuildHttpClient>(); }

If you have a moment to retarget this at main, I'd still merge it.
