title: Set default build agent VSTS
body: <p>How can I select what pool (or agent) a CI build uses?  When I select "manage" (next to default queue on the build summary) I see a list of pools, and I have privlegies to create a new pool "laptops" but no way to select this as the default. It always ends up in "Hosted" (and the net core .csproj is not supported there yet)</p>
